“electrostatic Charger for all U.S Army quartz fiber self-reading

In use, the charger would be positioned on a flat
surface while the end of the dosimeter was connected
to the charging contact on the top of the unit. The charger would
be oriented so that sufficient ambient light was reflected through the

The charge (i.e., the position of the hairline on the scale) was
controlled by turning the paddle-wheel like knob on the side of the unit:
clockwise to increase the charge or counter clockwise to decrease it.
