1. DC Voltage
a. Set the rotary switch at V DC.
b. Insert the test leads into the input jack.
c. Connect the test prods of the test leads in PARALLEL to the circuit to be measured.
d. Read the measured value from the LCD display.
2. AC Voltage
a. Set the rotary switch at V AC
b. Insert the test leads into the input jack.
c. Connect the test prods of the test leads in PARALLEL to the circuit to be measured.
d. Read the measured value from the LCD display.
WARNING: Before taking any in-circuit resistance measurement, remove power from the circuit being tested
and discharge all the capacitors.
C. AC+DC Power/Watt Measurement
1. Connect the test leads to the voltage source in parallel with the load.
2. Clamp on one of the wire to the load.
3. Select the range to Voltage AC or DC, and check the voltage reading.
4. Select the range to Current AC or DC, and check the current reading.
5. Select appropriate Watt range 40KW (0 - 250V, 0 - 400A) or 240KW (0 - 600V, 0 - 400A).
6. Read the value shown on LCD in KW (AC+DC).
D. Frequency (Hz) Measurement
1. Set the rotary switch at Hz.
2. Insert the test leads into the input jack.
3. Connect the test prods of the test leads in PARALLEL to the signal or circuit to be measured.
4. Read the measured value from the LCD display.
E. 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
