MAINTENANCE, REPAIR AND TROUBLE SHOOTING
MAINTENANCE AND REPAIR
There are no user-serviceable parts in the 1" Meter Series meters except the batteries.
Battery Replacement
When the “Lo Batt” indicator appears, the batteries should be changed. Six alkaline AA cells are required. To change the batteries, first remove the
four screws which hold the top cover in place. Be careful not to lose the washers. Move the top cover to one side and remove the foam retainer
which covers the battery tray. Remove the old batteries and replace them with fresh ones, taking care to follow the polarity indicators in the battery
tray. Replace the foam retainer, then put the top cover back in place. Put the four screws with washers back and tighten them firmly.
TROUBLE SHOOTING
PROBLEM
PROBABLE CAUSE
TRY
Blank Display
Batteries dead or incorrectly installed

Empty or partly filled pipe
Excessive air pockets or foaming
Rearrange piping to ensure full pipe
Flow but no flow rate reading
Heavily coated electrodes
Remove meter and wipe electrodes

Display
The display reads flow rate and accumulated total, in the units for which it was ordered. The top line is total, the bottom line is rate, and indicators
give the units (ac-ft, GPM for instance.) Empty or partially-full pipe is automatically detected and is indicated by a reading of “-EP-”.
Battery
Estimated battery life is approximately one year. Results may vary depending on the application. On the battery-powered 1" Meter Series there are
low-battery indicators (“lo bat”) when the battery voltage drops below a certain point. Batteries should be changed within four weeks of the
appearance of this indicator.
