Measuring AC or DC Current
Turn power OFF, break circuit, insert Meter in series, turn power
on.

To avoid personal injury or damage to the Meter:
Never attempt to make an in-circuit current measure-
ment when the open-circuit potential to earth ground
is 1000 V.
Check the Meter's fuses before testing. (See “Testing
the Fuses”.)
Use the proper terminals, switch position, and range
for your measurement.
Never place the probes in parallel with a circuit or
component when the leads are plugged into the
current terminals.

Measuring Frequency
The Meter measures the frequency of a signal. The trigger level is
0 V ac for all ranges.

To avoid electrical shock, disregard the bar graph for
frequencies >1 kHz. If the frequency of the measured
signal is >1 kHz, the bar graph is unspecified.
To exit frequency, press yellow button or turn the rotary
switch.
In frequency, the bar graph shows the ac voltage accurately
up to 1 kHz.
Select progressively lower ranges using manual ranging for a
stable reading.
