When “ ” is displayed, please replace the batteries in time to ensure
measurement accuracy.
Replacement steps:
1) Turn the function dial to the "OFF" position, and remove the test leads.
2) Unscrew and remove the battery cover to replace the batteries and fuses.
Warning: Before opening the rear cover or battery cover of the meter,
switch off the power supply and remove the test leads.
1) Clean the meter casing with a damp cloth and mild detergent. Do not use
abrasives or solvents!
2) If there is any malfunction, stop using the meter and send it for maintenance.
3) The maintenance and service must be implemented by qualified professionals
or designated departments.
4) Resistance measurement can be used to check the built-in 1A and 10A fuses.
Operation (Picture 18a): Insert the red test lead into the or terminal.
Insert the red probe into the
mA/
μ
A
input terminal to measure the resistance.
If the LCD displays “OL”, the 1A fuse is blown. Insert the red probe into the
A
input terminal to measure the resistance. If the LCD displays “OL”, the 10A
fuse is blown.
