The display of the calibrator is shown in Figure 3. The menu bar is used to setup the display to perform the desired function. Table 3 explains the different parts of the display: Table 3: Display Functions No. Name Description 1 Primary Parameters Determine what parameter is going to be measured or sourced. The available options are: VOLTS, TC (thermocouple), RTD, FREQ (frequency), PULSE, PRESSURE, mA, and mA 2W SIM.
In the output home menu there are three active options, [MENU], [LIGHT] and [STEP] or [RAMP]. The first two options work the same as in the input home menu. The third option is selectable in the Auto Function Menu and is used to turn on and off the selected auto function. See Section 4.2, Using the Automatic Output Functions. Also leaving this menu or pressing the Home button will stop the auto functions. The pulse home menu also has three active options, [MENU], [TRIG], and [COUNTS].
The auto off main menu contains the options [AUTO OFF], [NEXT], and [DONE]. The [AUTO OFF] option is used to turn the automatic shutoff on and off and set the amount of time the unit needs to stay dormant to shut off. [NEXT] and [DONE] both return to home menu. When the calibrator is in the frequency or pulse mode, the frequency level menu is added after the main menu. The options available in this menu are [FREQ LEVEL], [NEXT], and [DONE].
2.3 Cursor control / Setpoint control The output value can be controlled by the four cursor control arrows on the keypad. By pressing one of the arrows a cursor will be added to the display under the last digit of the output value. The left and right arrow keys are used to select which decade to be changed in the output value. The up and down arrow keys are used to increase, decrease, or ramp the output value. The menu bar will change to the setpoint menu with the touch of any one of the four arrow keys.
3. Using Measure Modes 3.1 Measuring volts and frequency The calibrator can measure volts or frequency on these jacks. To make the desired measurements, follow these steps: 1. Select the [CONFIG] option from the main menu. 2. Select the desired parameter for measurement. 3. Connect leads as shown in Figure 5. VOLTS IN + MEASURE / SOURCE 3W mA+ – -0.001 V MENU + V Ω Hz – 4W mA– TC LIGHT Figure 5. Measuring Volts and Frequency with Input/Output Terminals 3.
3.3 Measuring mA with Loop Power To test a 2-wire, loop powered transmitter that is disconnected from wiring, use the loop power function. This function activates a 24V supply in series with the current measuring circuit. To use this option proceed as follows: To measure mA with loop power follow these steps: 1. Use the [CONFIG] option from the main menu to select mA IN LOOP. 2. Connect leads as shown in Figure 7. +– MEASURE / SOURCE 3W mA+ 4W mA– + V Ω Hz – TC Figure 7.
The calibrator can also measure the mV of a Thermocouple, which can be used along with a table in case the corresponding TC type is not supported by the calibrator. To do so, proceed as above and choose mV from sensor types. TC PLUG Note: The TC wire used must match the thermocouple type being calibrated. MEASURE / SOURCE + – 3W mA+ + V Ω Hz – 4W mA– TC Figure 8. Measuring Temperature Using Thermocouple Terminals 3.
3.5 Measuring Pressure Note: The MC1010 is compatible with BETA Calibrator Pressure Modules. The accessory BPPA-100 is required for pressure measurement. Note: Pressure is not read from modules with frequency or pulse train mode enabled. Note: On high pressure modules engineering units normally associated with low pressure ranges such as, inH2O, cmH2O, etc. are not valid selections. Selecting one of this units with a high pressure module attached will cause the display to read "----".
3.4-1 Zeroing with Absolute Pressure Modules. To zero, adjust the calibrator to read a known pressure, such as barometric pressure. To adjust the calibrator, follow these steps: 1. Enter the pressure zeroing menu. 2. Select [ZERO ]. [SET REFERENCE ABOVE] will appear. Enter the pressure using the keypad. 3. The calibrator stores the Barometric zero offset in non-volatile memory. The zero offset is stored for one absolute pressure module at a time.
4.2 Using the Automatic Output Functions There are two automatic output functions, step and ramp. The selected function can be turned on and off using the Output Home Menu. The Automatic Output Function parameters can be set in the Auto Function Menu. Parameters include: 1. Which auto function will be available (Step or Ramp). 2. The Auto Function Time, time between steps for step and time to get from over one limit to the next for ramp. 3.
4.3-1 HART™ Resistor Selection The MC1010 can be set-up so that the 250 ohm resistor required for Hart™ configuration devices resides inside the MC1010. Enabling the MC1010's internal 250 ohm resistor eliminates the need to manually add a series resistor during a Hart™ calibration process. NOTE: When the MC1010's internal 250 resistor is enabled, maximum load driving capability drops from 1000 ohms @ 20mA to 750 ohms @20mA. Enable/Disable Procedure 1.

Switch to input/output control and select output [OUT]. 3. Connect the leads for the voltage source terminals, as shown in Figure 14. 4. Enter the voltage using the keypad. + MEASURE / SOURCE 3W mA+ UUT 4W mA– + V Ω Hz – TC – Figure 14. Connections for Sourcing Voltage and Frequency VOLTS OUT 0.
4.7 Sourcing a pulse train The calibrator can produce a pulse train with an adjustable number of pulses at a desired frequency. For example, setting the frequency to 60Hz and the number of pulses to 60 would produce 60 pulses for a period of 1 second. To source a pulse, use the same connection as for frequency, and proceed as follows: 1. Select the [CONFIG] option from the main menu and select pulse from the primary parameters. 2. Choose the desired unit and enter the frequency using the keypad. 3.

To connect 3- or 4-wire transmitter, use stacking cables, as shown in Figure 17. 4.9-1 Custom RTD A custom curve-fit PRT may be entered into the calibrator for sourcing and measuring. To do so follow these steps: 1. Select the [CONFIG] option from the main menu. Select RTD and set sensor type to CUSTOM. 2. Enter the RTD custom setup main menu, and select [SET CUSTOM]. 3.
Hyper Terminal, to enter single commands. Typical RS-232 remote configurations are shown in Figure 18. COM PORT USB PORT OR F1 F2 7 8 9 4 5 6 1 2 3 – 0 . F3 HOME CE ENTER Optional RS-232 or USB Cable (See section 7.4) Figure 18. Calibrator-to-Computer Connection 5.1 Setting up the RS-232 Port for Remote Control Note: The RS-232 connection cable should not exceed 15m unless the load capacitance measured at connection points is less than 2500pF.
5.2 Changing Between Remote and Local Operation There are three modes of operation of the calibrator, Local, Remote, and Remote with Lockout. Local mode is the default mode. Commands may be entered using the keypad on the unit or using a computer. In Remote mode the keypad is disabled, and commands may only be entered using a computer, but choosing [GO TO LOCAL] from the menu on the calibrator display will restore keypad operation. In Remote with Lockout, the keypad can not be used at all.
Overlapped Commands Commands that require more time to execute than normal. The command *WAI can be used after the overlapped command to tell the calibrator to wait until the command finishes before executing the next command. For example: TRIG; *WAI Triggers the pulse train. Once the pulse train has been triggered, the calibrator can proceed to the next command. Sequential Commands Commands that are executed immediately after the are entered. This type includes most of the commands. 5.
5.3-4 Calibrator Status Status registers, enable registers, and queues provide status information on the calibrator. Each status register and queue has a summary bit in the Serial Poll Status Byte. Enable registers generate summary bits in the Serial Poll Status Byte. The following is a list of registers and queues along with their function. Serial Poll Status Byte (STB) The STB is sent when the calibrator responds to the *STB? command. Figure 24 demonstrates how it functions. Cleared when power is reset.
7 6 5 4 3 2 1 0 PON 0 CME EXE DDE QYE 0 OPC PON Power On. Set to 1 if power was turned on and off before the Event Status Register was read. CME Command Error. Set to 1 when the calibrator receives an invalid command. Entering an unsupported RTD type may cause such an error. EXE Execution Error. Set to 1 when the calibrator runs into an error while executing is last command. A parameter that has too significant figures may cause such an error. DDE Device-dependent Error.
Table 5: Common Commands Command Description *CLS *CLS (Clear status.) Clears the ESR, the error queue, and the RQS bit in the status byte. Terminates pending Operation Complete commands *ESE Loads a byte into the Event Status Enable register. *ESE? Returns the contents of the Event Status Enable register. *ESR? Returns the contents of the Event Status register and clears the register. *IDN? Identification query.

*IDN? Returns the manufacturer, model number, and firmware revision of the Calibrator. For example: *IDN? will return MARTEL, MC1010, 250, 1.00 *OPC Enables the Operation Complete setting in the ESR. This setting makes it possible to check if an operations is complete after it has been initialized. For example this operation could be used with the command TRIG. *OPC? Returns 1 when all operations are complete, and causes program execution to pause until all the operations are complete.
5.5-2 Calibrator Commands CAL_START Puts the calibrator in calibration mode. The main display will say CALIBRATION MODE and a calibration menu will be displayed on the terminal. CJC_STATE Turns Cold Junction Compensation (CJC) on or off, when the calibrator is in thermocouple (TC) mode. The command is used by adding ON or OFF after it. For example: CJC_ STATE OFF turns CJC off. CJC_STATE? Tells whether the Cold Junction Compensation in thermocouple mode is turned on or turned off.
CPRT_COEFC This command is used for entering a custom RTD into the calibrator. The numeric value entered after the command will be set as the first coefficient of the polynomial used by the custom RTD. For example: CPRT_COEFC -5.8019E-12 enters -5.8019e-12 as coefficient A. CPRT_COEFC? Returns the number which was entered for the first coefficient of the polynomial used in the custom RTD. Using the example above CPRT_COEFC? Would return: -5.
Returns the value for the resistance in custom RTD. The above example would return: 1.000000E+02, OHM FAULT? Returns the error code number of an error that has occurred. The command may be entered when the previous command did not do what it was meant to do. For example, if a value for current output is entered that is bigger than the supported range (0-24mA) FAULT? Would return: 103 which is the code number for an entry over range. Refer to the Error Codes table for more information on error code numbers.
FREQ_UNIT? Returns the frequency unit currently being used by the frequency and pulse modes. FUNC? Returns the current mode of the display. For example if the calibrator is set to volts FUNC? Would return: DCV LOCAL Restores the calibrator to local operation if it was in remote mode. Also clears LOCKOUT if the unit was in lockout mode. MEAS Sets the display to measure mode. The command is followed by any of the parameters except for pulse and mA sim, which are source only.
PRES_UNIT? Returns the pressure units. For example if the unit on the display is psi the command will return: PSI PULSE_CNT Sets the number of pulses the calibrator will produce when it is triggered while in pulse mode. For example; PULSE_CNT 3000 will set the number of pulses to 3000. PULSE_CNT? Returns the number of pulses in the pulse train. Using the above example, the returned value would be: 3000 REMOTE Puts the calibrator in remote mode.
RTD_WIRE? Returns the number of wires used in the RTD connection. SIM Sets the output for current simulation. This command also switches the calibrator into mA simulation mode. A number and a unit must be entered after the command. For example: SIM 5 MA sets the current simulation at 5 mA SIM? Returns the output of the current simulation. With the example above, the output would be: 5.000000E-03, A TEMP_UNIT Sets the temperature unit for sourcing and measuring RTD and TC.
VAL? Returns the value of any measurement taking place on the display. For example, if the display is measuring 10V, then VAL? will return: 1.000000E+01, V ZERO_MEAS Zeroes the attached pressure module. Enter the zeroing value in PSI after the command when zeroing an absolute pressure module. ZERO_MEAS? Returns the zero offset or the reference value for absolute pressure modules.
