Parameter Calibration - PeakTech 4055 MV Bedienungsanleitung

4.14. Parameter calibration

* The instrument is calibrated before shipment, but some specifications may change a bit lot during long
time of use. To ensure the accuracy, the instrument should be calibrated termly.
* Users may regain the accuracy of the instrument by operating the keyboard to calibrate the main
specifications without removing the cover of the instrument.
4.14.1. Enable calibration:
* After booting, the calibration is in off state, and the generator could not be calibrated without inputting
calibration password, this is a way to protect calibrated parameters which may be changed carelessly.
* To enable calibration, select sine wave and then press【Shift】【Cal】-key, the calibration password
displayed as 0, input calibration password 1900, press 【N】-key to enable calibration.
4.14.2. Parameters calibration:
* Press 【Menu】-key to display calibration value on the left, and calibration sequence number on the right
when setting calibration conditions automatically.
* Adjust calibration value to calibrate present selected calibration option and make the output expected.
* Continue to press 【Menu】-key and the calibration sequence number will increase step by step, users
could calibrate all those options respectively, which is shown in the following list.
* During calibration process, press 【Cal】-key at any time then press 【Menu】-key to return the
calibration sequence number to 00.

4.14.3. Disable calibration:
* After finishing the calibration, press 【Cal】 key and there display 1900, press any numeric keys then
【N】 key to store the calibration parameters, disable calibration and exit the process.
* During the calibration process, if wrong calibration occurred, press 【Freq】 key at any time to disable
calibration and exit without storing calibration parameters.
* After rebooting, the generator automatically recalls and uses the calibration parameters stored during last
calibration.
