Input Protection:
0.25A, 250V fuse (for the measurement range below 200mA)
10A, 250V fuse
(for the measurement range below 10A)
Measuring method
(1) Insert the red test lead into the μA mA or 10A terminal and black test lead into the COM
terminal. (Select 10A for high current, and select μA or mA for low current less than 1A)
(2) Press
【
I-
】
key to select DC current measurement, and make test lead series connected with
object being measured.
(3) Press
【

or
【

key , and select current measuring range manually. Press
【
AUTO
】
key to lock automated measuring range
.(
【
AUTO
】
key enables you to switch ranges between uA
and mA. 10A range can only be selected by pressing
【▲】
key. )
(4)
If the “Over” light on, which means the measuring current value exceeds current range, press
【
▲
】
to select a higher range until a normal reading show up.
(5) Reading is shown as the measuring current on the display.
Note:
Before make device series connected with measured circuit, please turn off the power of
circuit.
Please use correct terminal when measuring. If you can’t estimate the current value,
please start from the high range of current.
Continue measurement is allowed if ≤5A; the measuring time should be ≤10 second and
interval time should ≥ 15 minutes to meet safe use
when
the current is between
5A to
10A
.
To avoid possible damage to the device and fuse, never place the testing leads in parallel
with any circuit or component when the leads are plugged into the current terminals.
When current measurement completed, first power off, then disconnect testing lead
with tested circuit and remove testing lead away from the input terminals of the Meter.
Fuse replacement
1. Cut off the power, disconnect the testing wire.
2. Rotate fuse holder with screwdriver counter-clockwise to pop-up the fuse
3. Replace fuse with the same specification
