OPERATION
Measuring AC or DC Voltage
•
Insert the test leads into the input terminals (red to VΩmA and black to COM).
•
Turn the range selector to ACV range.
•
Connect the test probes with the power or load being measured in parallel, and the
polarity of the point touched by the red test probe displays.
Notes:
•
If the voltage to be measured is unknown, choose the maximum measuring range
(600V) and reduce it step by step until a satisfactory reading is obtained.
•
If the input voltage >600V (AC/DC), the buzzer will continuously beep indicating
measure range is at it’s limit.
•
If the input current >10A (AC/DC), buzzer will continuously beep indicating
measure range is at it’s limit.
•
Disconnect the probes from the circuit under test when changing the range.
•
If the Display shows “OL”, it indicates the measured voltage is out of range. In this
case, turn the range selector to a higher range.
•
At mV position, press SELECT to enter frequency measurement (10Hz - 1MHz).
Measuring DC Current
•
Insert the black test lead into COM terminal. If the current under test is ≤ 200mA,
insert the red test lead into the VΩmA terminal. If the current is higher, insert the
red test lead into the 10A terminal.
•
Turn the range selector to AC/DC range, and connect the test probes in series
with the circuit to be measured. The polarity of the point touched by the red test
probe together with the measured value is displayed.
