MAIN
Setting an output: Use the LEFT & RIGHT buttons to select the
digit you want to change then press the UP or
DOWN to change the digit.
The digit selected is indicated with an
underscore underneath.
Output Protection: The voltage monitor detects when the output has been overloaded or subject to a
short circuit. The unit will immediately reduce the output to 0Vc (approx.) and display
an
“ERR” message on the LCD. When the problem is resolved the unit will recover
back to normal.
Best Stability: For the most accurate and stable output it is highly recommended to run the unit from
the batteries with no external DC power input. This helps avoids any ground loop
noise entering the system.
Screen Messages:
“CHG”
- Batteries are charging (also displays the charge current).
“FULL”
- Batteries are now fully charged.
“OVER”
- The Battery charge current exceeded the maximum allowable.
“OK”
- The main voltage output is functioning and is accurate.
“ERR”
- An irregularity has been detected on the main voltage output,
e.g. an external short circuit or over-current may have pulled
the output low.
“BT”
- Running on Batteries
“DC”
- Running on external DC supply
“COMMS”
- Serial comms is active
