2. To test FS1, plug a test lead into VΩHz input terminal, and touch the probe to the A input
terminal. The display should indicate between 0.0 to 0.2Ω. (Bussmann KTK-10
recommended). If display reads higher than 0.2Ω, replace the fuse.
Fuse Replacement
Refer to the following figure to replace fuse:
Use only a fuse with the amperage, interrupt, voltage, and speed rating specified.
Fuse rating : 10A , 600V, Fast
Replacing Fuses
Warning
To avoid electrical shock, remove the test leads and any input signals before replacing the
battery or fuses. To prevent damage or injury, INSTALL ONLY quick acting fuses with the
following Amp/Volt current interrupt rating :
Fuse : 10A, 600V, FAST.

Performance Tests
The following performance tests verify the complete operability of the Meter and check the
accuracy of each Meter function against the Meter’s specifications.
Accuracy specifications are valid for a period of one year after calibration, when measured at an
operating temperature of 18°C to 28°C and at A maximum of 80% relative humidity.
To perform the following tests, it is not necessary to open the case, no Adjustments are
necessary. Merely make the required connections, apply the designated inputs, and determine if
the reading on the Meter display falls within the acceptable range indicated.
If the Meter fails any of these tests, it needs calibration adjustment or repair.
Testing the Display
Rotate the dial from the "OFF" position to any other position. Check the LCD display segments
when all segments are displayed. Compare the display with the example in Figure 2.
