- Page 17 Exchange of fuse Be sure to check the ratings of the fuses, before connecting the AC power cable to the AC LINE connector of the Tester. The fuse holder is structured in the AC LINE connector. To check the fuse ratings, remove the fuse holder cap by using a screwdriver as illustrated below. Take out the fuses and check their ratings. After checking the ratings, put back the fuses into the cap and insert the cap into the fuse holder sufficiently − that is, until the cap clicks. When the fuse in present use has blown out, replace it with the spare one after eliminating the cause of the fuse blow. When you need further fuses, be sure to use fuses of the correct ratings. Nominal AC line voltage Fuse ratings 100V 250V 0.5A S.B. 5.2 x 20 200V 250V 0.3A S.B. 5.2 x 20 WARNING ・Do not use a fuse of incorrect ratings. Never attempt to run the Tester by shorting the fuse circuit with a wire.

- Page 18 Operating Procedure Procedure Before Test Before turning on the instrument power switch, check that both pointers of the meter are indicating the "0" scale position. If they are not indicating the "0" positions, adjust them to this position with their mechanical zero controls. If the instrument power has been on, turn it off and wait for several minutes and then check the meter. After thoroughly reading and noting the items of Section 3.2 "Precautions for Operation, " turn on the POWER switch and proceed as explained in this section. At the instant the power switch is turned on or off, the meter pointer may deflect irregularly. This is not an abnormal indication. Allow approximately 10 minutes of heat-run period so that the instrument operation is stabilized. Perform "zero adjustment" and "infinitive adjustment" as follows: Without connecting any item between the OUTPUT terminals 1 ( OUTPUT and GND terminals ), press the TEST ON button to set the instrument to the TEST ON state, and adjust the black pointer to the center of the "∞" scale position with the "∞ ADJUST" semi-fixed potentiometer at the rear panel. − 14 −...
