6. TROUBLESHOOTING
# No display.
Check position of the battery jumper J2 ( see interface board layout page 10 ) & check
battery contact connections. Replace battery.
# Display ghosting under external power.
The LCD display will “ghost” when the instrument is powered from an external 24Vdc
power supply, this is corrected by including two ¼ watt resistors (1.2K & 3.3K) on the
input power source as shown below.

The instrument has not been fully programmed after power up, enter the program mode &
enter program parameters, be sure to exit the program mode before the 4 minute no data

input power source as shown below.
# Scaleable pulse output counts on after flow has stopped.
The scaled pulse output has exceeded its output limit of 8Hz. Allow the memory buffer to
catch up or increase the pulse value - number of litres etc. per pulse, (clause 4.5, p12.)
# Display shows random characters.
The instrument may have taken an electrical “hit”, press the processor reset button (p10).
