Wiring Condition
Normal
No ground wire detected
Live and neutral conductors are reversed
Other conditions
Any wiring abnormality will prevent the CA10 from performing tests to the full
extent of its abilities. For example, in the absence of a ground wire the analyzer
can only measure the circuit's phase voltage and voltage drop. Furthermore,
the CA10 cannot detect the voltage between two live lines, multiple concurrent
faults, or reversed neutral and ground conductors.
OTHER FUNCTIONS
Backlight. Pressing the
display backlight. If no button is pushed for 30 seconds, the backlight will turn
off automatically. You can turn off the backlight manually by pressing the
button again.
Auto Power Off (APO). A 30-minute APO function is automatically enabled
when the CA10 is powered on. When APO is enabled (indicated by a clock icon
( ) at the upper left of the display), if no button is pushed for 30 minutes the
CA10 will automatically power off to extend battery life.
To disable the APO function, press and hold the FUNC button while pressing the
button to power on the unit. The clock icon will not be displayed.
Data Hold. Pressing the HOLD button freezes measurements of voltage
parameters on the larger, lower readout. Other measurements cannot be held.
To release the hold, press the HOLD button again.
