Function Buttons Correction of Zero correction for DC measurement This function allows the user to set the magnetization effects to zero when measuring DC. It must be performed after each high amplitude current measurement. With no conductor inserted into the clamp, press and hold the "Z / F* key (approx. 3 seconds) until a beep sounds and the ZERO symbol oD appears on the display.
Press the "MAX / MIN" button to display the minimum or maximum values one after the other. Press and hold the button for more than 2 seconds fo exit MAX / MIN mode. Back light: Press the button to change the background Activate / deactivate lighting. It turns off automatically after about 10 seconds of inactivity. ‘Work light: Press and hold this button for more than 2 seconds to switch the work light on or off.
Other Functions AC voltage measurement with low-pass fleeter "LPF" Helpful" function allows the clamp meter to filter interfering signals of over 60 Hz. These signals can lead to inaccurate measurements. The meter filters these signals and only measures the voltage signal. ae Measurement with LPF: “He Set the rotary switch to 600A, 60AorV. Press the "Z / F" button three times until 3 appears on the display. Now you can connect test leads and start measurement.
Low impedance voltage measurement (Low Z) LoZ mode allows you to measure AC voltages with a low impedance (approx. 300 kQ). In this mode, the multi meter lowers the internal resistance to prevent ‘phantom’ voltage readings. As a result, the circuit is more heavily loaded than in the standard measuring mode. Set the rotary switch to "Low Z" to use the function. The Low Z voltage measurement must not exceed 600 V.
Operating Instructions Insert and replace batteries Replace the batteries immediately when the symbol “CX” appears in the display. Disconnect the ; 78 meter from the power source. Remove the test leads from 7 5 the measuring device, loosen the screws on the back and & remove the lower half of the housing, replace the old batteries and screw the cover back on. Turn on/off the meter The device is switched on when the rotary switch (5) is set to a measuring function.
seconds and switch on the clamp meter at the same time. The symbol disappears. Restart after switching off the meter, the automatic switch-off can be red. Auto-ranging The meter automatically selects the measuring range that is best suited for the measurement performed. The measuring unit and resolution are adjusted at the same time. AC Zero Input Behavior of True-ems Meters Unlike averaging meters, which can accurately measure only pure sine waves, True-ems meters accurately measure distorted waveform.
Making Measurements AC! DC Current measurement The current is measured via the current clamp (2). The sensors in the current clamp detect the magnetic field created by current-carrying conductors. You can take measurements on insulated and not insulated conductors. The test leads should be disconnected from the measuring device when measuring current. Proceed as follows to measure the current: 1. Tum the rotary switch fo the comet current setting (60A / 600A). "DC" appears on the display.
» If several supply conductors {e.g. L1 and L2) are measured, the currents add up. » Center the conductor through the current clamp {above the markings) » Hold your fingers behind the tactile barrier. 4. The measured current is shown on the display. If current> 3A, the orange display lights up. 5. During AC current measurement, press display the frequency value or use the LPF function measurement.
Voltage Measurement A Voltage above 600 V cannot be measured! When measuring high voltage, pay special attention to safety to avoid electric shock or injury. 1. Set the rotary switch to 7. Press the "Z / F" key to change the AC or DC voltage measurement. 2. Plug the black test lead into the COM socket and the red test lead into the INPUT socket. 3. Then bring the test probes into contact with the points to be measured. 4. Read the result on the display. If the voltage Is> 80 V, the orange display lights up.
Frequency or Duty Cycle Measurements (Hz%) A Do not enter a voltage above 10 VI When measuring high voltage, pay special attention to safety to avoid electric shock or injury. 1. Turn the rotary function switch to Hz% and press the "Z / F" key to switch over the frequency or duty cycle measurement. 2. Plug the black test lead into the COM socket and the red test lead into the INPUT socket. 3. Connect the probes to the measuring points (connect § to the measured power supply or to the parallel connection).
Resistance measurement Q A Do not enter a voltage above 10 VI Make sure that the power supply to the circuit is disconnected and all capacitors are discharged. 1. Turn the rotary function switch to 2%¥ for resistance measurement. It displays "MQ" on screen. 2. Tum off the circuit under test. 3. Plug the black test lead into the COM socket and the red test lead into the INPUT socket. 4. Then place the test probes in contact with the points at which the resist acne must be measured. 5.
Continuity test) A Do not enter a voltage above 10 VI Make sure that the power supply to the circuit is disconnected and all capacitors are discharged. 1. Turn the rotary switch to 2% and press the "Z / F" key several times until +n appears on the display. The continuity test is now active. 2 Plug the red test lead into the INPUT socket and the black test lead into the COM socket, 3. Connect the probes to the circuit or component under test. x 4.
Capacitance measurement 1. Remove power from the circuit being tested. Turn the rotary function switch to %% , press the "Z/F" key to cycle through from resistance to continuity to capacitance function. 2. Connect the black test lead to the COM terminal and the red test lead to the "INPUT" terminal. 3. Connect the probes across the circuit or (capacitance) component to be tested. 4. View the reading on the display.
Diode Test 1. Tum the rotary function switch to iH. Press the "Z/F" key to cycle through from resistance (to continuity fo capacitance) to diode function. Remove power from the circuit being tested. 2. Connect the black test lead to the COM terminal and the red test lead to the INPUT terminal. 3. Connect the black test lead to the cathode side and the red test lead to the anode side of the diode being tested. 4. Read forward bias voltage value on the LCD. 5.
Temperature measurement 1. Turn the rotary function switch to C/T position. Press "Z/F" to select °C or °F, the display reflects the chosen temperature unit. 2. Insert the K-type thermonuclear into the meter, the positive pole (red) of the therm couple into the "INPUT" input, and the negative pole (black) into the "COM" input. 3. Contact the thermonuclear probe with the measurement object, then the reading appears on the display. 4. Connect the temperature probe with the testing point.
Non-contact AC Voltage Detection (NCV) A Make sure that all measuring sockets are free. Remove all test leads and adapters from the meter. This function only serves as an aid. 1. Turning the rotary dial to any position, hold down the "H/NCV" for more than 2 seconds, "click" a sound, the meter shows the "NCV" character and then enter the NCV detection function. 2. Then the NCV probe will be approached the detected point gradually. 3.
