DANGER
The maximum input voltage and current are 600 Vrms, 60 Arms.
If the display value exceeds 600 V or 60 A, immediately stop
measurement, cut the power to the line being measured.
If measurement is continued exceeding the maximum input, the unit
will be damaged and cause a serious accident.

3.4 Selecting the Range
(1) Setting limits
Voltage range: 15/30/60/150/300/600 V
Current range: 1/2/5/10/20/50/100/200/500 mA, 1/2/5/10/20/50 A
Active power, reactive power and apparent power ranges: combination with
voltage and current range. See Section 11.2
Current peak range: six times of current range
Active input limit (accuracy assuring limit) : 5% to 120% for range. (5% to
100% only in 600 V range) (for current peak value, 5% to 100% for range
or 90 A peak value)
Indication limit: 130% for range (for voltage, current, active power), 110 %
for range (for current peak) In case of over this limit, the mark shown on the
left is displayed (this means out of range).
・ During integration (the RUN indicator is lit or flashing), the range cannot be
changed ("Err.012" is displayed). Before changing the range, press the
RESET
key to reset the integration value (the RUN indicator goes off).
・ During holding the displays (the HOLD indicator is lit or flashed) the range
cannot be changed ("Err.016" is displayed). Before changing the range,
pressing the
HOLD
key or
SHIFT
→
HOLD
keys to release the hold state (the
HOLD indicator goes off).
・ The range which was already set to OFF is skipped.
(See Section 4.12, "Selecting Range".)
(2) Settings
When the range select function is set (SEL lamp is lit), ranges that haven't
been set are skipped.
