CURRENT MEASUREMENT
1. Ensure that “Data Hold” button is not in pressed position.
2. Set range switch to the ACA 1000A range. If the display
indicates one or more leading zeros. Shift to the 200A range
to improve the resolution of the measurement.
3. Press the trigger to open the transformer jaws and clamp
one conductor only, measurements can’t be obtained when
two or more cables are clamped at the same time.
4. Display reading is flow the conductor AC current.
RESISTANCE MEASUREMENT
1. Connect red lead to “Ω”, black lead to “COM”.
2. Set the range switch to desired Ω range.
3. If the resistance being measured is connected to a circuit, turn
off power and discharge all capacitors before measurement.
4. Connect test leads to circuit being measured.
5. Read resistance value on Digital Display.
CONTINUITY TEST
1. Connect the BLACK test lead to the “COM” jack and the RED
to the “VΩ” jack (Note: The polarity of the red test lead is
positive “+”).
2. Set the range switch to range
3. Connect the test leads across the load to be measured.
4. If the circuit resistance is lower than about 30±20Ω,
the built-in buzzer will sound.
BATTERY REPLACEMENT
1) Battery and fuse replacement should only be done after the test
leads have been disconnected and power is off.
2) Loosen screw with suitable screwdriver and remove case.
