Checking the Safety Pips
To check the limits please connect:
- Left jack
of the Calibration Unit with the Safety Pips’s ground.
- Right jack of the Calibration Unit with the Safety Pips’s coil cord connector using the
banana plug adapter.
Select sequentially with the marked leaver of the rotary switch each position of the
Calibration Unit’s left scale (Lo, OK, OK, OK, Hi and Hi).
The Safety Pips must indicate the results corresponding to the selected position of the rotary
switch.
