I purchased a WLS-PVA200 from your Amazon store to use on my 1972 GE garden tractor with a 36V LiFePo4 battery. So far I have successfully set it up with the correct Amp-Hour, Max Voltage, and Low Voltage settings. However, while scanning through the settings, I found additional ones that are undocumented in the user manual and I can’t figure them out.

The user manual has AH (Amp-Hour), FU (Full Voltage, V = U on an 8-segment display), HU (High Voltage), LU (Low Voltage), and HA (High Amperage). But there is also CU, AP, AC, and AU in my meter. Can someone tell me what these settings are, and how they might be set for a 36V 100 Ahr battery?

Thank you,
