IR - Improvement to insulation resistance to improve execution speed.
LL - Improved the LL test method to allow reverse energization of high turns ratio parts. High turns ratios create weak shorts which gave poor LL results.

ZB - Fix to ZB Compile process to deal with STAT 0020.
HPDC - Fixed error code 0020 on IR and DC-EHT following a MAGI test. The issue was caused by the trip system latching during the shutdown process and not clearing for the HPDC test.
DCRT - Fixed DC ramp test reporting pass when it should fail.
LL - Fixed LL accuracy issue caused by running open circuit compensation.
LSB LPB ZB - Added Offset measurements to the LPG, voltage channel and current channel to improve stability of LSB, LPB and ZB measurements.
R - Improved compensation model for the resistance test.
TRL - Fixed TRL trimming issue on secondary caused by failing to preserve the shunt for the polarity measurement.
SELF TEST - ID1020 now has the filter state set properly so does not report false fails.
SELF TEST - Adjusted the self-test limits for GN01 open and close timing to reduce false self-test failures
KNOWN ISSUES - Issues being worked on for future release
Improvements to capacitance accuracy at very low capacitance <10 pf
Fails DCRT - occasional status errors or mis-reads - Suggest HPDC as alternative.
Fails ACVB - occasional status errors or mis-reads. Suggest HPAC as alternative.
Fails DCVB - occasional status errors or mis-reads. Suggest using HPDC as alternative
HPDC - Occasional Status errors and false fails when close to measurement limit.
Self test 1000 - Can give false fails on some units. If your unit fails self test on this test ONLY then the unit is deemed good. This will be fixed on the next release.
