5.0 Calibration
The iQUBE can be calibrated using the 920i front panel or Revolution III . The following sections describe the
calibration procedure for each of the calibration methods.
Figure 5-1. CALIBR Submenu
5.1 920i Front Panel Calibration
The CALIBR submenu (under the SCALES menu,
see Figure 5-1) is used to calibrate the
920i and the
iQUBE at the same time.
Three calibration methods can be used to trim the load
cells:
• Theoretical
• Cal-Match
• Manual trimming
5.1.1 Theoretical Calibration
To perform a theoretical calibration of the iQUBE
using the 920i front panel, press the Theoretical
Calibration softkey. The dead load value is captured
and the cells trimmed based on the capacity and
sensitivity values entered for the cells. Scale capacity
is set at the total of the load cell capacities.
5.1.2 Cal-Match Calibration
To perform a Cal-Match calibration of the iQUBE
using the 920i front panel, do the following:
1. Place the indicator in setup mode (display
reads Scale Configuration ) and remove all
weight from the scale platform.
2. With the SCALES menu highlighted, press
the down key to show the CALIBR parameter.
3. From the CALIBR parameter, press down
again to show a list of configured platforms
and select the platform to be calibrated.
4. Press down to go to the test weight parameter
( WVAL ). By default, the test weight value is set
to the total load cell capacity. Use the numeric
keypad to enter the test weight, then press
enter .
5. Press the Cal-Match softkey to continue
