Operation
Always check the battery before any measurements. Set the function and range switch
on the desired range, the
icon appears on the LCD when the battery capacity is low.
Also, pay attention to the
icon besides the JACK for test leads. It indicates the
maximum rating. Don’t apply measurements more than that.
DC voltage measurement
1. Connect the red test lead to the
“VΩmA”
jack and the black test lead to the
“COM”
jack.
2. Set the range switch to the desired DC voltage range (V
).
3. Connect the test leads across the device or circuit to be measured. Read the
voltage value on the LCD display along with the polarity.
Measure voltage
WARNING
: Do
NOT
test more than 500V voltage, which might damage the internal
circuit and harm your safety
.
If the actual voltage to be tested is unknown before
measurements, you should firstly set the meter at the highest range, and then
gradually lower the range according to the reading. If the LCD only display “1”, it
means the measured value exceeds the current range, you have to level up the
range.
In each range, the input impedance is 10MΩ. Such load effect will result in
measurement error when measuring the high impedance circuit. While if the
