Calibration/Validation; Check Standard Mode - palintest Photometer 7500 Operation Manual

7. Calibration/Validation

Your Photometer 7500 Bluetooth is delivered with a
calibration certificate validating the performance of the
instrument as it leaves Palintest.
We recommend annual service and calibration of all
photometric instruments in normal use.
The Photometer 7500 Bluetooth also includes an automatic
routine to validate analytical performance using certified
Palintest Check Standards. Accessed via the Mode menu, the
Check Standard Mode provides a field method of ensuring
your instrument is operating within defined specifications and
also a troubleshooting method for unexpected results.
Every Palintest Check Standards set is supplied with certified
values expressed as %T (Transmission), derived from
traceable reference materials. Acceptable tolerances are
defined on the certificate and are automatically specified
within the Photometer 7500 Bluetooth.
