Victor VC60B+ Instruction Manual

INSULATION TESTER
INSTUCTION MANUAL
一、GENERAL
This instrument adopts the DC Voltage convertor of low
consumption and high converter ratio inductance energy
storage, to change the 9V Voltage to 250V/500V/1000V DC
Voltage. It uses digital bridge to make the insulation
resistance measurement had the features of user-friendly,
high extent range, backlight display, data hold and auto
power off. The whole instrument is stylish and superior grade
in appearance and high stable in performance, it can be
operated by both hands through using a shoulder strap. It is
most suitable for the needs of insulation resistance check,
such as electric, cable, electrical and mechanical equipment,
telecommunication equipment and electrical facilities.

四、OPERATION DESCRIPTION：
Open the battery case and set up 6pcs of 5# batteries
1、
(see the following pictures), note the polarity of
batteries.
2、Press the button of"POWER".
3、 Select the right voltage (250V/500V/1000V/AC750V) according
to the requirement of measurement.
4、Select the right range (RANGE) (except AC750V), according to
the requirement of measurement.
5、Connect the electrode of the measured object to the relative
terminal of the instrument.
6、When measuring cable, connect G Terminal to the protection
loop.
Press the button of measurement and start it, turn the
7、
knob right to lock the button; when the value is stable,
get the reading from LCD.
Connect the input line "E" to the ground of the
