Warnings
•
Do not input a voltage higher than 1000V. Higher voltage may be measured but it
risks damaging the meter.
•
When measuring high voltage, extra care should be taken to avoid an electric
shock.
•
After completing all the measuring operations, disconnect the connection between
the test leads and the circuit under test.
AC & DC CURRENT
•
Insert the red test pen into the µA, mA or A terminal and the black test lead into the
COM terminal.
•
Set the rotary switch to the position as shown below. Press
SELECT
to choose
the required AC or DC to be measured. Connect the test leads to the test circuit in
series.
•
Directly read the measured current values on the display. True virtual values are
displayed for AC measurement.
•
Press the function button
MENU
to enter a sub-menu
option in which basic AC or DC
current measurement can be
modified.
•
Press the directional buttons to
choose between the options.
•
The red cursor button indicates
the selected item.
Warnings
•
Before connecting to the test circuit in series, turn off the power to the circuit first
and discharge all the high-voltage capacitors.
•
Use proper input terminals and functions for measurement. If the current size
cannot be estimated, the range of large current should be measured first.
•
When the test lead is inserted into the input terminal of current, do not connect
its test probe to any circuit in parallel as it will blow the fuses within the meter and
damage the meter.
•
After completing all the measuring operations, disconnect the connection between
the test leads and the circuit under test.
RESISTANCE
•
Insert the red test lead into the Ω terminal and the black test lead into the COM
terminal.
•
Set the rotary switch to the measurement
Ω nS
where Ω is the default
resistance measurement. Connect the test leads to both ends of the measured
resistance.
•
Directly read the measured resistance values on the display.
Warnings
•
If the open circuit of the measured resistance or resistance value exceeds the
