MEASUREMENT

Power On :
Rotate the function switch to keep it from staying in the “OFF” position.

The system will be auto off when it has no operation after 3 minutes.
Before testing, you must make sure that the resistance under test does not have any voltage. When the voltage exceeds 5 volts or the probe is connected to a power supply of more than 5 volts, a warning message will be displayed.
Select scale range :
There are 5 scale range “200.0mΩ”, “2000mΩ”, “20.00Ω” , “200.0Ω” and “2000Ω” could be selected by rotating the function switch. 2000Ω scale uses the 1mA to test. 200.0Ω & 20.00Ω scales use the 10mA to test. 2000mΩ & 200.0mΩ scales use the 100mA to test. The screen will display date, time, test current and maximum resistance.
The measurement function
Press “TEST/STOP” button to measure the resistance value.

Press “MAX/MIN” button to get the max value or min value in the measurement process. Press “HOLD” button to keep the value of resistance. Press “TEST/STOP” button to stop the measurement.
Record saving function
When the measurement is finished, press “SAVE/ ENTER” button to save the result of measurement. At the same time, the last line will display the number of record. The memory can record up to 200 records.
Minor function
Press “ESC/SEL” button and hold over 1 second to enter the minor function.

Use the “UP” and “DOWN” button to move the function selection cursor, and press “SAVE/ENTER” to enter the minor function, and press “ESC/SEL” button to return back to the main page.

Date / Time ADJ
