G: Before taking any in-circuit resistance measurement, remove power
·rcuit being tested and discharge all the capacitors.
3.3. Resistance and Continuity Measurement
3.3.1. Set the rotary switch at n
3.3.2. Insert the test leads into the input jack.
3.3.3. Connect the test prods of the test leads to the two ends of the resistor or
circuit to be measured.
3.3.4. Read the measured value from the LCD display.
3.3.5. If the resistance is lower than 40 n , a beeping sound shall be heard.
3.4. Frequency {Hz) Measurement
3.4.1. Set the rotary switch at Hz.
3.4.2. Insert the test leads into the input jack.
3.4.3. Connect the test prods of the test leads in PARALLEL to the signal or
circuit to be measured.
3.4.4. Read the measured value from the LCD display.
3.5. Relative Reading Measurements
The zero button also can be used to make a relative measurement. Once the
button is pushed, the current reading is set to zero and a zero symbol shall be
displayed on LCD. All the subsequent measurement shall be displayed as a
relative value with respect to the value being zeroed. Press the zero button again
to return to normal mode. But this function is disabled if MAX/MIN function is
enabled. Please watch for symbol displayed on LCD.
NOTE:
1. The ZERO button is disabled if ohm and continuity or Hz function is selected.
2. LCD displays relative numerical value without bargraph.
3.6. Holding the LCD Reading
Press the HOLD button, then the reading shall be hold and kept on LCD.

NOTE:
The HOLD button is disabled if ohm and continuity function is selected.
3.7. Finding the MAX/MIN Value
Press the
MAX/MIN
button to enable the maximum and minimum values to be

recorded and updated during measurement. Push the button once, the
maximum value shall be displayed and updated. The LCD display toggles
between the MAX and MIN values. To exit MAX/MIN function, press and hold
the MAX/MIN button for more than 2 seconds. If MAX/MIN button is pressed, the
ZERO function will be disabled and the ZERO symbol will disappear from LCD.
NOTE:
The MAX/MIN button is disabled if ohm and continuity or Hz function is
selected.
