General Maintenance
Cleaning
Periodically wipe the case with a damp cloth and detergent; do not use abrasives or solvents.
Calibration
Calibrate your calibrator once a year to ensure that it performs according to its specifications.
Replacing the Battery
Please change the battery when the LCD indicates
Turn off the power of the Calibrator, When you change the battery, and screw off the breechblock on the battery cabinet cover, then take off it and instead the fresh battery.
Replacing a Fuse
Warning！
To avoid personal injury or damage to the calibrator, use only a 0.125A 250V fast fuse.
Fuse 1 is probably blown if:
. In the V output mode, with the test leads removed from the calibrator, the display flashes OL.
Fuse 2 is probably blown if:
In the mA input mode, the calibrator always reads 0.000, even with a signal applied.
