MAINTENANCE and TROUBLESHOOTING

Maintenance

There are no user-serviceable parts in the WMP-Series
meters except the batteries in the WMP104.
Battery Replacement. When the "low bat" indicator
appears, the batteries should be changed. Either six AA
alkaline cells are required, or two C lithium cells with
integrated wiring harness, depending on power option
ordered with meter.
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 or pack.
Warning!
Use Extreme Caution not to pinch wiring
or other assembly parts under the
housing seal—this may cause an ingress
of water, voiding the product warranty.

• For units with AA alkaline batteries, remove the old
bat teries from the battery tray and replace them
with fresh ones, taking care to fol low the polarity
indicators in the battery tray.
• For units with the optional C lithium batteries,
carefully unplug each of the two battery wiring
harness connectors. Slip the batteries out from
under the elastic retainer, and replace them with
the new batteries. Reconnect each of the two wiring
harness connectors. The connectors are indexed for
correct installation.
Replace the foam retainer, and then put the top cover
back in place. Replace the four screws and washers, and
then tighten them securely using cross-pattern to evenly
compress the gasket.

accordance with Federal, State, and Local
regulations.
