F4, MT-1
or
MT-2
open. Connect a voltmeter from
MT-1
to
MT-
2,
turn control ON and check voltage. If 95 - 110 VAC is not
present, replace fuse, tighten connections, or add
13
to
100
VAC
, kVp compensation transformer.
2500 ohm kVp meter compensation resistor OPEN. Turn
control OFF, remove
fuse 4
and measure resistance across the
2500 ohm resistor. If the resistor is OPEN, replace it. NOTE:
If the 2500 ohm resistor heats up or opens, you may have a
short from
MT-1
to
MT-2
to a winding on the autotransformer.
The only way to correct this is to remove
MT-1
and
MT-2
leads
from the terminal strip and install a
13
to
100 VAC
kVp meter
compensation transformer.
NOTE:
For units manufactured after June 2006. MT1 – MT2
compensation transformer is separate from auto transformer
windings.
