5 Performance Tests and Calibration

Input-A Terminal Test

This test determines if the input warning of the A current terminal test is
functioning properly. The multimeter sounds an alerting beep when the
test lead is inserted to the A input terminal but the rotary switch is not
set to the corresponding A location. The display indicates a flashing AErr
annunciator until the test lead is removed from the A input terminal. This
warning alert is not available in T1/T2 temperature measurements mode.

Input-mA Terminal Alert Test

This test determines if the detected input voltage level is within the
accepted boundaries when the μA/mA input terminal is connected. The
multimeter sounds an alerting beep when the μA/mA input terminal
detects a voltage level of higher than 1.6 V. The display indicates a flashing
CErr annunciator until the test lead is removed from the μA/mA input
terminal.
The alerting beep will not be impacted even if the beep function is disabled.
