3. Set the rotary switch to an appropriate measurement position A
... range for DC or A~ for AC. When the value is unknown
always start from the max range 20 A.
4. Break the current path to be tested. Connect the red test lead to
the more positive side of the break and the black test lead to the
more negative side of the break.
5. Turn on power to the circuit. The measured value shows on the
display.
Note
• Displays 1 selected range is overload, it is required to select a
higher range in order to obtain a correct reading.
Resistance measurement
1. Insert the red test lead into the HzVΩ terminal and the black test
lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position in
Ω range.
3. Connect the test leads across with the object being measured.
The measured value shows on the display.
Note
•
The test leads can add 0.1Ω to 0.3Ω of error to resistance measure-
ment. To obtain precision readings in low-resistance measure-
ment, that is the range of 200Ω, short-circuit the input terminals
beforehand and record the reading obtained. This is the addi-
tional resistance from the test lead.
Temperature measurement (see fig 4)
1. Insert the multi socket into the mA and HzVΩ terminals.
2. Set the rotary switch to the °C position.
3. Insert the temperature probe to the multi socket.
4. Place the temperature probe to the object being measured.
