25 JUL 2023

AT5600 Firmware v1.004.052 / User Manual V25

GUI      
Fixed active test name jumping to "CTY" on reset   OPP 8973
Added FPMM key code support and soft-key access (future release)

SELF TEST
Enhanced Surge self-test
Fixed occasional Self-Test Overall Fail when all tests have passed.
Remove self-test conditioning routine.
Added desaturation to GN02 and GN12 self-test timing.

COMPENSATION
Improved compensation storage to store individual range combinations instead of shunt compensation.
Improved the download speed of programs by streamlining compensation storage.
This improved indexing will speed up program load.
Program Load was slow if you had large numbers of compensations stored. The delay was not comms, but the COMP recall after load.
PLEASE NOTE - This upgrade will also clear all previously stored SC+OC compensations from the unit. OPP11165
Improve impedance compensation speed.
Improve open circuit compensation by using ratio of integrated voltage and current instead of integrated impedance.
This should fix erroneous occasional OC comp fails OPP 11173,11154, 11237.
Fixed HPAC, HPDC, ILK, and MAGI open circuit compensation application
Improved pass/fail reporting for short circuit compensation.

TESTS
API       Fixed result return to server for API (future release)
API       Fixed API not reporting busy (future release)
C2        Fixed negative capacitance match (C2) results.
ILK       Leakage Current (ILK) accuracy enhancement
ILK       Adjusted under-ranging configuration to allow lower ranges on ILK.
ILK       Fixed compensation failure on 100kOhm shunt for ILK OC

SURG   Surge Learning Simplification
SURG   Improved the surge magnitude learning algorithm.
VOC     Fixed VOC test causing unit reboot. Certain test cases on centre tapped parts previously could cause a reboot at 40-60Hz OPP11075

KNOWN ISSUES - Currently being addressed for next release
OC compensation - a small % of unit may mistakenly report OC COMP fail on this version.
This is currently being addressed.
If you see this issue please contact us.

FUTURE DEV - Coming Soon
FRONT PANEL MEASURE MODE - run individual tests from the front panel.
E-dt – Volts uSec test for pulse transformers..

SELF TEST
Self Test - Fixes some false fails on some self-tests (typically ID #1011, 2023, 2023, 4041) when unit is functionally good.

11 NOV 2022

AT5600 Firmware v1.004.012 / User Manual v23

INTERFACE / GUI
SOUNDS - Added Beeps to indicate PASS/FAIL for compensation for a better user experience - follow the same settings as Run Pass/Fail sound.
DC1000 error codes - fixed bugs causing some possible DC1000 Error codes to be incorrect.

SELF TEST
ID 1021  - Adjusted limits for Self-Test ID 1021 to stop false failures.
Fixed an issue with infinite self-test time on faulty hardware.

TESTS
R  - Improved Compensation process for Resistance. Added range locking for resistance short circuit compensation.

KNOWN ISSUES - IN PROCESS FOR IMPROVEMENT
HPDC - false flagging on 0200 is some cases causing fail and 30 second test time.
