Load measurement

Put down the device on the windshield in such a way that the extremity of the wiper arm arrives in front of the measure system.
Push and release the ON / OFF button without applied effort.
Wait for the ZERO SEARCH:OK indication.
Apply the extremity of the wiper arm on the measurement system; the display indicates the value and the load unit.
When the measure is steady, push on MEMORY button to maintain the display to this value. Clear this value by pushing once again.
The device cuts itself automatically after three minutes of inactivity.

Changing the battery

Unscrew and remove the closing plate.
Disconnect battery connector.
Take the battery out, change it.
Engage the battery ( minus pole to the center ). Set the battery connector.
Take the battery in, replace the closing plate and screw back again.

Load calibration

To start the procedure, hold MEMORY down. Push and release ON/OFF. Wait until OK appears. Release MEMORY.

If the difference between measured value and real value is not important you may use a short calibration procedure. At starting up apply a known charge and verify the indication given by the device. Correct with the gain adjust potentiometer to obtain the exact value and turn the device off. Repeat operation to check.

Complete calibration:
- for a charge of 0 of the displayed value is approximately 35.
- for a charge of 1 kgf the displayed value must be: the given value for 0 kgf plus 450, for example 35 + 450 = 485. Adjust the gain potentiometer to perform the condition: displayed value at 0 kgf + 450 = displayed value at 1 kgf.
- Redo with 0 kgf and 1 kgf to check the condition. If not, adjust once again.

To quit push on ON/OFF. To go to UNIT CHOICE push on MEMORY
