CAUTION
Handle the tester with care as the delicate instrumentation it incorporates can easily be damaged by shock of
improper handling procedures.
To prepare the tester for use; set the tester on a level bench or platform with an AC or DC power source
available.
CAUTION
DO NOT force-tighten control valves; damage will occur to the needle point of the valve.
Set power ON-OFF switch to OFF, close four Vacuum and Pressure control valves and set VACUUM and
PRESSURE selector valves to off.
CAUTION
Power source voltage must be within limits specified in paragraph 1-6; or damage will cause a blown fuse.
If AC power is used, connect AC power cable to power connector on rear panel. Connect single-phase adapter
cable to free end of AC power cable if single phase power is used.
If DC power is used, connect DC power cable to power connector on rear panel and, observing polarity,
connect clips of DC power cable to DC power source.
