9. Turning The RigRat On And Off
Turning The RigRat On
With the instrument turned off, press and hold the button until LCD display starts a countdown, and
then release. During startup, the battery, buzzer, and LEDs are tested, and then it performs self-testing
of its other functions. When the main measurement screen appears, the instrument is ready for
calibration or use.
Note1: The type number is given on the LCD display during startup, refer to clause 2 for more
details about use restriction.
Note 2: When the battery’s charge falls below a preset voltage, the instrument warns you by showing
a critical error message, and turn off automatically in 3 seconds. You should charge the battery before
turning it on again.
IMPORTANT!
If a major error that prevents the RigRat from functioning is found during startup, the message
“Contact Service” is shown on the display. The instrument should be shut off and serviced.
Note: During a pumped BW RigRat’s startup, startup pauses and the display instructs you to place your finger
over the pump inlet to test the pump. Leave the inlet covered until instructed to remove your finger.
