7. Making Measurements
This section describes some common applications for your instrument and alert you to some
considerations to keep in mind when making measurements.
7.1. Measuring DC Voltages
Warning !!
*
Do not try to measure a voltage greater than 1000 Volts DC since it may damage your
instrument and expose yourself to a severe to shock hazard.
*
Do not touch circuits or a part of circuits when measuring voltage above 35 V DC.
Follow these steps to measure DC Voltage:
1. Press FUNC
– Switch "V ="
2. Press RANGE
– Switch to select the range as required to the voltage level to be measured. If
you do not know the voltage level, start with the range selection to the highest voltage position
and reduce the range position as needed to get a reading.
3. Plug the black test lead into the COM terminal and the red test lead into V/
terminal.
4. Connect the test leads to the DC Voltage source your want to measure.
Notes:
*
If display is negative, "-" appears on the left of the display
*
For the most accurate measurement, select the lowest possible voltage range without getting an
overload reading.
*
Input impedance: 10 MOhm
7.2. Measuring AC Voltage
Warning !!
*
Do not try to measure a voltage greater than 1.000 volts AC since it may damage your
instrument and expose yourself to a severe shock hazard.
*
Do not touch the circuits or a part of circuits when measuring high voltages above 25 V AC
rms
.
Follow these steps to measure AC Voltage:
1. Press Function-Switch "V ~". AC appears on the display.
2. Press RANGE-Switch to select the range as required for the voltage level to be measured. If you
do not know the voltage level, start with the range selection to the highest voltage position and
reduce the range position as needed to get a reading.
3. Plug the black test lead into the COM
– terminal and the red test lead into V/
- terminal.
4. Connect the test lead to the AC voltage source you want to measure.
