Metering
1.4.1
The equipment is fitted with two output kilovoltmeters, which sense both the positive
and negative outputs simultaneously. Both instruments have a single range of 0-30
kilovolts. Each division on the instruments represent 1 kilovolt. The individual
meters are captioned as follows:
a.
Positive kilovoltmeter:
+ kV DC
(In red)
b.
Negative kilovoltmeter:
- kV DC
(In blue)
1.4.2
The equipment is fitted with two output milliammeters, which sense both the positive
and negative output currents simultaneously. The individual meters are captioned as
follows:
a.
Positive milliammeter:
+ mA DC (In red)
b.
Negative milliammeter:
- mA DC (In blue)
The output milliammeters are dual range as follows:
Range 1:
0 - 10mA
Each division being 0.5mA
Range 2:
0 - 1.0mA
Each division being 0.05mA
The range change on the milliammeters is achieved by means of an impulse push-
button which is coloured white and located on the front panel of the equipment. The
rest position is Range 1 and the activated position is Range 2.
1.4.3
The voltage and current monitoring systems for each output are totally independent
of each other.
