POWER Light
The green
POWER
light is located at the right side of the instrument near the top. When
the instrument is turned on, the light illuminates.
LOW STAIN Light
The yellow
LOW STAIN
light is to the left of the
POWER
light. It is off under usual
operating conditions; however, when the Hematek Stain Pak contains sufficient reagents
to stain only about 20 slides, a weight-sensing device activates the circuit and illuminates
the light. The Stain Pak should be replaced at this time.
Power Module
The power module is located on the rear of the instrument; on one side of the module is
the panel that contains the line cord receptacle, fuse, and power switch. The power module
converts the line current coming into the instrument to 12 volts DC, which is the voltage
within the instrument.
