8. Measurements
8-1 Connection
Connect the instrument according to Fig.7,8,9.
DANGER
This instrument is designed to measure the earth-to-line voltage
90 ~ 264V and the line-to-line voltage up to 440V (50/60Hz). Do not
exceed the maximum allowable input of any measuring range.
WARNING
● Power on the instrument before connecting to the measuring point.
● Prior to a measurement, confirm that the instrument isn’t in the
Sleep mode. If it is in the sleep mode, set the Function Switch to

instrument. Otherwise, it may influence on the test results.
8-2 Voltage Measurement
The instrument automatically measure voltages when it detects input of
voltage.
DANGER
Indication of “Lo V” is displayed on the LCD when the measured
voltage is less than 80V; “Hi V” is displayed with audible warning when
the measured voltage is 450V or higher. Disconnect the instrument
from the measuring point immediately when “Hi V” is displayed on the
LCD, and stop further measurements. The Test Button is disabled
while “Lo V” or “Hi V” is displayed on the LCD, and RCD test cannot be
performed.
