Charge Terminal Alert Test
This test determines if the charge terminal alert is operating
properly.
The meter sounds an alert when the terminal
detects a voltage level of more than 5 V and the rotary
switch is not set to the position. The meter sounds
an alert beep and the primary display flashes the “Ch.Err”
until the lead is removed from the terminal.
