3.6 Loaded Calibration

Use the following procedure to perform a loaded calibration proceed as follows.

1. Access Loaded Cal. from the Dynamic Cal. menu.

2. Perform 10 lifts with a known load in the bucket at decreasing rpm settings, starting at the max RPM

with the bucket closed.

The Loaded Calibration menu includes the following data:

3 2 Back side cylinder pressure or differential pressure

43Time

5 3 Back side cylinder pressure or differential pressure

64Time

7 4 Back side cylinder pressure or differential pressure

XNTime

Y N Back side cylinder pressure or differential pressure

Setting Description

Time Time elapsed during the lift, obviously the lower this value, the greater the speed of the lift.

TP1 value Indicates the piston’s pressure transducer reading.

TP2 value Indicates the rod’s pressure transducer reading (if installed).

KnownLoad1 Set the known load for calibration 1: insert the value according to the machine’s capacity, keeping

in mind the decimals to be displayed, and the resolution preferred (this value can also be set at

the completion of the calibration).

LT1

point

Displays the number of lifts performed at decreasing speed, which will correspond to the number

of points recorded in loaded calibration 1 table, (refer LT1 xxxx: -xxxxx)

LT1 xxxx: -xxxxx Allows viewing the complete loaded calibration 1 table. It is possible to scroll through the table by

selecting the index number.
