Note: Unplug any thermocouple probes from the
thermocouple input sockets before making any other
types of measurements.
Voltage Measurements
1. Connect the red test lead to the "V
" jack and the black test
lead to the "COM" jack of the multimeter.
2. For DC measurement, set the Function switch
" V " position. For AC measurement, set the
Function switch " V " position.
3. Connect the other end of the test leads to the device or circuit
being measured.
Resistance & Continuity Measurements
1. Set the Function switch to the resistance position.
2. Remove power from the device or circuit under test.
3. Connect the test lead to the "V
" & "COM" jacks.
4. The beeper sounds once, if the resistance being measured is
less than 30 Ohms.
Current Measurements
1. Set the Function switch anywhere from 430µA to 10A depending
on the range.
2. In the 10A position, connect test leads to "A" and "COM" jacks.
In lower ranges, connect test leads to "mA µA" & "COM" jacks.
3. For AC measurement, press the
button, and an AC icon will
appear on the display.
4. Connect the multimeter in Series with the circuit being measured.
