3. Measurement of low-resistance (see figure 6)
1. Insert the red test pen in OHM jack (red hole), withanother end
connected with the alligator clip; and insert the black test pen in
COM jack (black hole).
2. Push tje rotating switch to the gear OHM and connect test
pen in parallel with the circuit to be measured.
3. Press down “TEST”, after waiting for 2s, view the current
measured value on the display.
4. To save the current measured value during measurement,
just push the button “SAVE”.
5. To ensure the measurement accuracy, the test pen of the
instrument should be returned to zero prior to measurement
so as to remove the error caused by the test pen; detailed
operation procedures are as follows: short ciricuit the alligator
clip of test pens, after pressing down “TEST”, the screen
displays the resistance value less than 2,00 OHM, and after
anothert long press on “COMP” 3s, the symbol “ZERO” appears
on the right upper corner of screen and the screen displays
“0,00 OHM”, indicating successful to return zero.
Note:
- It is required to ensure prior to measurement that the object to be
measured is electrically neutral, or otherwise resulting in inaccurate
measurement.
- Prior to test, the instrument will judge if the object to be measured is
electrified higher than 25V,if so, LCD displays high-voltage symbol and
measurement is forbidden.
- When the resistance exceeds the maximum display range, the instrument screen
would display the symbol “>”± and the maximum resistance of the current range.
