Calibration Overview
Calibration is a procedure that ensures that the power supply will work
properly, with parameters specified within Technical Specification section.
Before initiating the calibration procedure, the following conditions must be
assured:
§
§
disconnect any loads connected to the power supply and turn it on
§
§
let the power supply turned on for 1 hour, with no loads connected before
you start the calibration procedure
§
§
calibration ambient temperature must be 25
0
C
§
§
ambient relative humidity must be less then 80%.
Recommended calibration interval is 1 year.
Important note!
In order to perform the calibration procedure, a digital multimeter is needed. It
must have the following characteristics:
Voltage resolution: 0.1 mV
Current resolution: 0.01 mA
Acurracy: 0.01 %
Calibration Security Code
To prevent accidental or unauthorized calibration procedures, the power supply
has a calibration security code. This security code is optional, so you may have
it or not. The power supply will work properly in both cases.
Security code may contain numbers (0..9), small letters (a..z) and spaces (“ “).
Any of these characters may be used as the first character in security code.
Security code may contain up to 11 characters. But it is not necessary for you to
use all 11 characters for the security code.
The security code is saved in non-volatile memory and it doesn’t change when
you turn on or turn off the power supply.
When delivered, power supply has the following security code: 0000
In order to initiate the calibration procedure, first you must unsecure the power
supply (if a security code is set).
