5.3.2.1. Mode Selection
MX08 AD instruments have three operation modes which are;
Count Mode
:
Filtered and normalized ADC count data is transmitted in this
mode. The calibration is performed at PLC, if any.
Weighing Mode
:
Unipolar weight data in calibrated weighing unit is transmitted.
This mode is compatible to OIML R76 and EN 45501.
Force Mode
:
Bipolar or unipolar force measurement data in calibrated force
unit is transmitted.
Select scale operation mode and polarity. Click
Write to Digitizer
button to save your mode
selection.
Default calibration of MX08 AD instruments is Count Mode and 10 mV unipolar input signal
range.
If you select the count mode, there is no scale build and instrument calibration. Each
MX08 AD instrument is adjusted in production to increase the calibration accuracy. MX08
AD input signal ranges and their external resolutions are seen in Table 4.2.

5.3.2.2. Scale Build
The scale capacity, increment and unit must be introduced to the MX08 AD instrument
before performing calibration in Weighing and Force measurement.
