Set up & Calibration of the Series 1-L is achieved in 4 stages:
1) Zero Angle sensor setting (75% LED Lit in Calibrate mode).
2) Zero Pressure sensor setting for no-load condition (100% LED Lit in Calibrate mode).
3) Data logger function On or Off control (75 & 100% LEDs lit in Calibrate mode).
4) Maximum Tipping Moment setting (50% LED Lit in Calibrate mode).
Make sure the machine data has been entered into the Series 1-L as described on the
previous page. Ensure that there is a clear area around the machine and that there is no
danger to personnel.
Position the magnet supplied, as shown, on
top of the display box using adhesive tape or
Blu-Tac to enable Calibration to be performed
(Stops inadvertent setting changes).

Stage 1 - Zero Angle Sensor
Place the machine on level ground. Lower the boom to the Horizontal position with No load.
The position of any Dipper or Extending Boom fitted does not matter at this stage as it only
zeros the Angle Sensor reading at Horizontal.
Ensure the magnet is fitted on the top of the display as shown above. The Display will be in
Indicator mode. (Probably just bottom green “Power On” indicator lit.)
Press and hold the RED test button for more than 3 seconds to enter the Calibrate mode. All
the LEDs come on to show it is now in Calibrate mode. Release the Red button and the top !
Red and bottom green Power On LEDs are lit, as well as the 50% Green LED.
!! DON’T REMOVE THE MAGNET !!
REMOVING IT, OR NO ACTIVITY FOR 100 SECS WILL EXIT THE CALIBRATE MODE.
Press the Red button momentarily. The 75% LED lights to show “Zero Angle Sensor” mode.
Press & hold the Red button for over 2 secs to make the Series 1-L Acquire and Store the
Angle Sensor reading representing the Horizontal Boom position.
Now release the button. All the LEDs should come on momentarily, then all but the Green
Power On LED go off before all the LEDs come on momentarily again to confirm the
Zero Angle has been acquired and stored. The unit will then go from Calibration mode to
Indicator mode with just the Green Power LED lit.
