Fuse Replacement
If the Fuses clear due to fault or overload, the fuses can be replaced as follows;
① Power off the Meter. Disconnect Test Leads from the Meter.
② Separate the Battery Cover from the meter.
③ Pull out one end of defect Fuse from Fuse Clip.
④ Replace with same size and ratings as the original fuse.. Fuse should be placed in center of
Fuse Clip and pressed into place.
⑤ Do not touch any other components besides the fuse.
⑥ Re-assemble the Battery Cover on the meter
⑦ Fuse Ratings and Dimensions are as below ;
[Fuse Rating and Dimensions]
500mA/250V 5mm × 20mm (FF)
1OA/250V 6.3mm × 32mm (FF)
Open Fuse Test
Select main menu "Resistance" key. Insert Test Leads into Resistance Input Terminals. Test
Lead Tips Connected to 10A Input or mA Input to check the Fuse Open status.
10A: 0.00Ω ~ 0.50Ω measurement
㎃: 100Ω ± 1Ω measurement.
6. Function Test and Calibration.
This chapter introduces Performance Testing and Calibration procedures. Performance Test
Procedure verifies the meter performs in accordance with the specifications of the meter.
Calibration procedure ensures that the meter performs correctly according to specifications
until next calibration time.

Calibration Description
This manual contains the procedure to check the performance of meter to determine if
calibration is needed.
Calibration of the meter does not require the case be opened and does not need calibration
on passive components. Meter calculates calibration coefficient parameters based on input
base signal. Calibration Coefficient values are kept in the internal memory until next
calibration time.
[Calibration Cycle]
Calibration is generally recommended once per year. Product accuracy is guaranteed only
when calibration is regularly conducted. If 1 year Calibration cycle is not kept, the meters
accuracy can’t be guaranteed.
[Suggestion on Calibration]
Meter specifications are guaranteed within the period from the last calibration until next
calibration time. Calibration needs to be completed for all functions to meet the specifications
