5. PREPARATION FOR A MEASUREMENT
WARNING
Make sure, before turning the instrument on, that the VOLTAGE
SELECTOR switches on the rear of the unit are properly set to the
positions in agreement with the local AC line voltage. If the agree-
ment is failed, the unit may break a fire or burning.
WARNING
Be sure to connect the ground prong of the power cord plug to
prevent danger. If grounding of the ground prong is impossible,
connect GND terminal to the ground post of the power line system.
Note: For safety, the measuring voltage cannot be output unless otherwise
the accessory shorting plug is plugged into the HV-EN connector on
the rear of the unit. During measurement, the shorting plug must
be kept plugged in
.
WARNING
Before trying to plug the shorting plug into the HV-EN connector,
be sure to turn the POWER switch OFF.
5.1 Preparation
Confirm the setting of the instrument in the order shown below.
1) Confirm that the VOLTAGE SELECTOR switches on the rear of the unit
are set to the positions in accordance with the local AC line voltage from
which the unit is powered (See 1.3 Setting the VOLTAGE SELECTOR
Switches.).
2) Confirm that the POWER switch of the unit is positioned at the OFF
(released) position. Note that if the switch is in the ON position, it is
depressed.
3) Plug the accessory power cord into the AC LINE receptacle on the rear of
the unit. Also, plug the plug on the other end of the cord into the
commercial AC line socket.
