Chapter 7 Transformer Auto Scanning Test
7.1 Introduction to scan test function
Automatic transformer test system consists of TH1901A/ TH1901B transformer
scanning box and TH2829X. It can test the following parameters: inductance (Lx),
leakage inductance (Lk), quality factor (Q), turn (TURN), phase (PHASING), stray
capacitance (Cx), DC impedance (DCR), AC impedance (ACR), impedance (Zx),
inductance balance (Lx-BALANCE), DC impedance balance (DCR-BALANCE),
short test (PIN-SHORT) and current bias (DCI-BIAS), etc.
TH2829X can realize the automatic conversion between transformer pins and
fixture pins, automatic test time of rescan interval setup, multi-group primary
winding test, multi-group leakage test, deviation compensation for test values,
PASS and FAIL count for test result, save and load function for test parameter,
repeat test for FAIL product, etc. TH2829X can test several transformers at the
same time.
7.2 Install and connect the scanning test system
Automatic transformer test system is the connection of TH1901A/TH1901B and
TH2829X, and the connection steps are as follows:
1. Use 36PIN double-headed cable (TH26016 transformer test control cable) to
connect the SCANNER socket on the rear panel of TH1901A/B and the SCANNER
socket on the rear panel of TH2829X as shown in the following figure.
NOTE: It is forbidden to plug the cable with electricity. Keep the direction
of cable be correctly routed.

2. If it is necessary to use the foot switch, connect the foot switch to the FOOT.C
