4mm banana plugs.
FUSE ASSEMBLY
Allows field replacement of the input current protection fuse with a small flat-blade screwdriver.
DISPLAY
3-1/2 digit liquid crystal display indicates the measured value of the signal applied to the input in mA or
mAs.
RESET SWITCH
Resets the display to zero after a mAs measurement has been made and the display reading has been
recorded.
MODE SWITCH
Selects either AC or DC measurement mode. The position of this switch depends upon the type of
current signal from the x-ray generator to be measured.

operate in the mA function. Only the 200 and 2000 ranges operate in the mAs function.
DISPLAY ZERO ADJUST
Trimmer potentiometer (R33) provides adjustment for a zero display reading with no signal applied to the
input jacks.
MA GAIN ADJUST
Trimmer potentiometer (R10) provides calibration adjustment of the mA function.
MAS GAIN ADJUST
