Calibration for dual and single transducer installations:
Calibration for Gauges with bargraph displays
The calibration mode is entered by the use of a “password”.
There are two magnetic switches, one located at each side of the display.
These switches are activated with the use of a magnet.
Switch activation is visually confirmed by the toggling of the closest bar on the dis-
play to the switch. If it is on it will turn off, if it is off it will turn on.
