Performing A System Calibration - Mantracourt DSC User Manual

Once you have connected the load cell, you should see 'believable' output values, in the "SYS" parameter displayed
in the parameter list pane. These values should correspond to mV/V assuming the device is in it's factory default
state.
For diagnostics the device has two sets of flags. One being latched and held within the devices non volatile memory
(FLAG parameter), the other being dynamic and volatile (STAT parameter).
Instrument Explorer provides a simple method of displaying and resetting of individual flags although these are held
within the device in FLAG and STAT parameters.
To quickly clear all the flags simply write zero to the FLAG parameter. Now if no problems exist all flags should in
their off state.
If any flags remain on then refer to Chapter 8 for flag definitions.

Performing A System Calibration

The values obtained so far are in mV/V units, these are factory calibrated and fixed to within 0.1% accuracy.
The device also contains two separate user-adjustable calibration parameter groups, these are termed "Cell" and
"System". Cell being used to convert from mV/V to a calibration value and System to convert this calibration value
to the required engineering units. The use of "CELL" is optional. We shall be using "System" for the following
exercise where we rescale the output value to read in units of your choice, and to calibrate precisely to your load
cell / system hardware.
Instrument Explorer provides Wizards to allow quick and simple calibration operations to be undertaken without the
use of a calculator. Wizards can be activated by simply selecting the required item from the Wizard menu.
Since we are now calibrating at system level we have a choice of two calibration methods:
Sys Calibration Table – This technique is used when a manufacturers calibration document is available for the
connected strain gauge. This normally gives mV/V to engineering unit values.
