Measurement Operation DC Voltage Measurement Figure 2 DC Voltage Ranges: 200mV, 2000mV, 20V, 200V, 500V Input Impedance: 10M 1. Plug the red test lead into the V mA terminal, then plug the black test lead into the COM terminal. 2. Set the rotary switch to the appropriate measurement in V range. - Page 11 AC Voltage Measurement (See Figure 2) 200V, 500V AC Voltage Ranges: Input Impedance: 1. Plug the red test lead into the V mA terminal, then plug the black test lead into the COM terminal. 2. Set the rotary switch to the appropriate measurement in V~ range.
- Page 12 DC Current Measurement WARNING Never attempt an in-circuit current measurement where the voltage between the terminals and ground is greater than 60V. If the fuse burns out during measurement, this may cause harm to the user and/or damage to the device. Use proper terminals, functions, and range for measurement.
- Page 13 7. When measurement is completed, disconnect the test leads from the object of measurement. NOTE If the value of voltage is unknown, use the maximum measurement position (10A) and reduce the range until proper readings are obtained. Resistance Measurement Figure 4 Resistance Ranges: 200 , 2000 , 20k , 200k , 20M , 200M...
- Page 14 the input terminals beforehand and record the reading obtained (reading X). This is the additional resistance from the test lead. Then use the equation: Measured resistance value (Y) - (X) = resistance result • For high-resistance measurements (>1M ), it may take a few seconds for the reading result to stabilize.
- Page 15 1. Plug the red test lead into the V mA terminal, then plug the black test lead into the COM terminal. 2. Set the rotary switch to the setting. 3. For forward voltage drop readings on any semiconductor component, place the red test lead on the component’s anode and place the black test lead on the component’s cathode.
- Page 16 Square Wave Output WARNING To avoid damage to the meter and/or the object of measurement, do not allow output terminals (red test lead) to surpass 10V. 1. Plug the red test lead into the V mA terminal, then plug the black test lead into the COM terminal. 2.
