TC100 1. Introduction The Martel TC100 is designed to be a simple to use, high accuracy thermocouple calibrator capable of either simulating or reading J, K, T, L, E, R, S, T, B, C, or mV thermocouple types. A standard thermocouple mini-connector along with screw terminals for bare wire makes connections easy while providing direct contact with the internal cold junction compensation circuitry.
1.2. Unpacking Your Calibrator Remove the packing list and verify that all equipment has been received. If there are any questions about the shipment please call Martel Electronics at 1-800-821-0023. When the shipment is received inspect the container and equipment for any signs of damage. Note any evidence of rough handling in transit. Immediately report any damage to the shipping agent. NOTE: The carrier will not honor any claims unless all shipping material is saved for their examination.
Double Insulated Electric Shock Fuse PE Ground Hot Surface (Burn Hazard) Read the User’s Manual (Important Information) Off On Canadian Standards Association The following definitions apply to the terms “Warning” and “Caution”. • “Warning” identifies conditions and actions that may pose hazards to the user. • “Caution” identifies conditions and actions that may damage the instrument being used. Use the calibrator only as specified in this manual, otherwise injury and damage to the calibrator may occur.
Warning To avoid possible electric shock or personal injury: • Do not apply more than the rated voltage. See specifications for supported ranges. • Follow all equipment safety procedures. • Do not use the calibrator if it is damaged. Before you use the calibrator, inspect the case. Look for cracks or missing plastic. Pay particular attention to the insulation surrounding the connectors. • Select the proper function and range for your measurement.
2. Accessories The following items are available for the TC100 calibrator. Item P/N AC adapter/charger 1001-9V (120V) 80013 (220V) 9V NiCd battery 1002-9V (must use with above charger) TC wire kit (J, K, T, E) 80029 TC wire kit (R, S, B, N) 80036 3.
Before beginning, become familiar with the keypad layout and the configuration of the input/output jacks. See Figure 1. In the basic or “as shipped” setup, the TC100 allows the user to step through all available T/C types (10 plus mV). In certain situations this may be confusing to infrequent users as to which type to use. The optional advanced setup mode allows a supervisor through password control to “blank out” or disable unwanted T/C types so that only the proper T/C types can be selected.
2. Select either Input or Output mode depending on whether you want to read a thermocouple or simulate a thermocouple signal. 3. Connect the appropriate thermocouple to the mini-connector or screw terminals on the top of the TC100. Note: for best accuracy, allow 3 to 5 minutes for the T/C connector (or wire) to stabilize to the same temperature as the connector block. 4. If you are using the TC100 in the output mode use the cursor control keys to select the decade to be controlled.
2. When operating in the thermocouple Measure Mode the TC100 can be used to read the temperature of a thermocouple probe. In this mode, the TC100 will detect an open circuit should the thermocouple junction malfunction. In this case, the display will indicate “OL”. It will also indicate “OL” if no probe is connected in the Input Mode. FIGURE 3 READING A THERMOCOUPLE PROBE 6.
7. Setpoint Feature The TC100 allows the user to program up to 3 setpoints for each TC type (including mV). to set the setpoints complete the following procedure: 1) Turn on the TC100 and select the Source Mode. 2) Select the TC type to be simulated and correct units (either °C or °F). Recall 3) Press to see what is currently stored in each of the 3 setpoints. 4) To store a new value adjust the output to the desired value then press the Set key. 5) Repeat steps 3 & 4 until all 3 setpoints are stored.
1) Place the TC100 in the measure mode. 2) Connect a thermocouple (or probe). 3) Clear the min/max memory by pressing both keys (min and max) simultaneously. The LCD will display “CLR” when the memory is cleared. 4) Allow the unit to log min. and max. for as long as required. Warning: You may want to disable the Battery Save feature before using the Datalogging Mode to prevent the TC100 from turning off prematurely. 5) At any time press the min. or max. to display the value stored.
9. Maintenance A. Battery Selection The TC100 operates on a standard 9V alkaline battery or an optional rechargeable 9V Ni-Cd battery. For most applications the 9V alkaline battery will suffice; however, in heavy use applications the 9V Ni-Cd may be a better choice. The 9V Ni-Cd battery supplied by Martel will offer approximately 7 hours of continuous use on a full charge (the alkaline battery will yield about 25 hours).
