6. HOW TO MAKE MEASUREMENTS
This section discusses some common applications for your meter, and
alerts you to some considerations to keep in mind when making
measurements.
6-1. Measuring DC /AC Voltage
WARNING: DO NOT TRY TO MEASURE A VOLTAGE GREATER
THAN 1000 VOLTS DC OR 750 VOLTS AC. YOU MIGHT DAMAGE
YOUR METER AND EXPOSE YOURSELF TO A SEVERE SHOCK
HAZARD.
Follow these steps to measure DC/AC Voltage:
1. Set the rotary switch to the desired voltage position with 5 steps:
200mV, 2, 20, 200V(DC/AC) and 1 000V(DC), 750V(AC).
2. Press the DC/AC button to toggle between alternating and direct
voltage.
3. Connect the meter in parallel with the load or circuit.
Notes:
• Due to the sensitive nature of 200mV & 2V AC ranges, your meter
displays a small value. This residual value will not affect the actual
measurements.
• Each of the five dc/ac voltage ranges presents an input impedence of
approximately 10M Ω in parallel with less than 100pF. AC voltage in
ac-coupled to the 10M Ω input.
