Description
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
Insert the red probe into the mA/μA 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.
2. Battery/Fuse Replacement (Picture 18b)
Battery: 4×1.5V AAA batteries
Fuse: F1 Fuse 1A 240V Φ6x25mm (mA/μA input terminal)
F2 Fuse 10A 240V Φ6x25mm (A input terminal)
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.
