NOTE: Input signal level must be higher than 0.5V (it is sensitivity).
5-5. DC/AC
µ
A or mA measurement
DC Current range is 200.0
µ
A/2000
µ
A and 20.00mA,/200.0mA and then 10A
range.
AC Current range is 200.0
µ
A/2000
µ
A and 20.00mA,/200.0mA and then 10A
range.
①
Turn off power to the circuit. Set the rotary switch to the proper
DC/AC
µ
A or DC/AC mA position.
②
Break the current path to be tested. Connect the red test lead to the
more positive side of the break and the black test lead to the more
negative side of the break.
③
Turn on power to the circuit. The measured value show on the display.
5-6. DC/AC 10A measurement
①
Insert the red test lead into the input terminal marked as “10A”.
②
The measuring procedure is same as that of 5-5 section..
Note:
●
For safety’s sake, the measuring time for high current should be
≤
10 second
for each measurement and the interval time between two measurement should
be greater than 5 minutes.
●
When current measurement has been completed, disconnect the connection
between the testing lead and the circuit under test.

Maintenance
6-1. Replacing the battery
When meter display
the battery must be replace to maintain
normal operation.
①
Disconnect and remove all test probes from any live source and meter.
②
Open the battery cover on the bottom case by screwdriver.
③
Remove old battery and snap new one into battery holder
6-2. Fuse replacement
