3.1 Preparative Procedures
3.1.1 Wearing Insulation Gloves
When handling the tester, be sure to wear insulation gloves in order to protect your-
self against high voltages. If you cannot obtain insulation gloves, please contact
Kikusui distributor/agent for them.
3.1.2 Grounding the Tester
Be sure to ground the tester. To do this, connect securely (using a tool) an earth line
to the protective grounding terminal on the rear panel of the tester. Unless the tester
is securely grounded, when the tester output is shorted to an earth line or to a con-
veyor or other device which is connected to an earth line or when it is shorted to the
AC line*
1
, the tester chassis can be charged up to the high voltage that can cause
electric shock.
For a description of the grounding method, see section 2.6, “Grounding (Earth)”
(Page 2-6 ).
*1 The term “AC line” here means the line on which the tester is operating. That is
the line to whose outlet the power cord of the tester is connected. It may be of a
commercial AC power line or of a private-generator AC power line.
3.2 Warnings and Cautions When Operating
the Tester
3.2.1 Before Turning ON the AC Input Power
Before turning on the AC input power, be certain that the TEST VOLTAGE control
knob is at the “0” position (fully counterclockwise position).
3.2.2 Connecting the Low Test Lead
For the connection method of the low test lead to the LOW output terminal of the
tester, see Fig. 3-1. Each time before using the tester, check that the low test lead is
not broken.
