Section 2 - Calibration and Bench Check
It is recommended that you perform a bench check on your instruments prior to installing them in
your application.
Calibration
A true calibration of the STA can only be performed at Moore Industries using specialized
equipment. We recommend that you check the calibration every year and notify Moore
Industries if you suspect a problem with the accuracy of your instrument.
However, sensor trimming increases the measurement accuracy of your instrument by matching
the reading of its actual input to its scaling. The STA o󰀨ers the use of a factory-congured
trimming feature (‘FCTRY TRIM”) or user-set, one-point or two-point (“USER 1 PNT” or “USER 2
PNT”) trimming.
Please refer to Section 4 of this manual for instructions to perform Input Trimming via Push
button panel or in Section 5 using the PC Conguration Software.
Likewise, output trimming increases the measurement accuracy of the STA by calibrating its
Analog Output to the device that is receiving the output. This ensures that the instrument is
being correctly interpreted.
Please refer to Section 4 of this manual for instructions to perform Output Trimming via Push
button panel or in Section 5 using the PC Conguration Software.
Bench Check
We highly recommend that you perform a bench check of your STA prior to installing it in the
eld. Doing this will ensure that it is operating within your expectations or requirements.
The bench check is a quick way to determine that your STA is functioning as expected.
Depending on your organization’s requirements, you may also be required to perform a complete
Proof Test on your STA. The instructions for the Proof Test can be found in Section 7 of this
manual.
As a prelude to performing the bench check you should congure your STA as it is to be used
in your nal application. Refer to Section 4 for the STA Front Panel Conguration instructions.
These instructions are used if you are conguring your STA by using the front panel push
buttons. Section 5 contains the instructions for conguring your STA using the STA PC
Conguration software.
The equipment necessary to perform a bench check can be found in Table 2.1.
