5. Preparation for Measurement
5. 1 Checking the battery voltage
Set the Range Switch to any position other than “OFF” without connecting
the Power Cord to the Power Connector.
When the Battery Mark shown at the upper right on the LCD is last 1 level
( ), the battery is almost exhausted. Replace or recharge battery
to continue measurements. The instrument operates properly even if
under such a low battery, and such a low battery status may not affect the
accuracy.
When the Battery Mark is vacant ( ), the battery voltage is below the
lower limit of the operating voltage. So the accuracy cannot be guaranteed.
No measurement can be performed even the TEST Button is pressed
down. Refer to Battery Charge and Replacement (=>P.71) and charge or
replace battery.
5. 2 Test Lead Connection
Insert the test lead firmly to the Connector Terminal on the instrument.
Connect the Line Probe (red) or Line Probe with Alligator clip (red) to
the Line Terminal, Earth Cord(black) to the Earth Terminal and Guard
Cord(green) to Guard Terminal. No need to connect Guard Cord when
establishing a guard is not necessary.
Refer to“How to use Guard Terminal”(=>P.69) in this manual for further details.
# DANGER
● If the TEST Button is pressed while the Range Switch is at a Range other
than “OFF”, high voltages may applied to the test leads and you may get
an electric shock.
● Do not connect the Earth Cord (black) nor Guard Cord (green) to the Line
Terminal.
Carefully read through “1. Safety Warnings” (P.4) in this manual.
