Batteries
NOTE: Low battery icon will appear when batteries
require replacement. Meter still functions properly for
several days after the icon appears. Neither calibration,
current total or totalizer quantities will be lost when you
replace batteries.
To Replace Batteries (refer to exploded view).
1. Unscrew meter cap (item 1, page 10). Use a strap
type oil filter wrench or large 5" jaw pipe wrench if
needed.
2. Insert a flat-head screw driver into the top slot (see
Figure 4) and gently pry up electronics module.
CAUTION: DO NOT get fluid or dirt in electronics area.

3. Remove old batteries and insert new batteries,
making sure battery polarity is correct, or meter damage
could occur (positive side facing up when installed).
4. As noted in Figure 5, reinstall O-ring on electronics
module. Align sensor receptacle in proper location. Press
module gently down into meter cover.
5. Thread on meter cap until hand tight. To check
tightness, there should be approximately 1/16" gap
between cap and ridge on outlet port. (See Figure 6).
If any meter components are damaged, they should be
replaced. See meter kits drawing on page 10 for correct
replacement part information before ordering.

Repair
Maintenance
Follow fluid manufacturer's recommended procedures for
handling and disposing of metered fluids.
Meter should be flushed between uses with water to
prevent chemicals from drying and plugging meter.
Thorough Cleaning (refer to exploded view)
If meter is plugged due to hardened chemical or debris, do
the following:
1. Drain all fluid from meter.
2. Unscrew meter cap (item 1, page 10). Use a strap type
oil filter wrench or large 5" jaw pipe wrench if
necessary.
3. Insert a flat-head screwdriver in the lower slot (see
Figure 7) and turn to pry up meter cover (item 6).
4. The meter chamber (item 8, page 10) can now be
removed.
5. Rinse all meter components with flushing fluid. DO
NOT submerge display assembly. Be careful not to
get any fluid or dirt in the electronics module.
Permanent damage to the electronics will occur.
6. Reassemble meter.
CALIBRATION NOTE: Over time, the chamber inside the
meter will wear, requiring the meter to be re-calibrated with
water. When this should be done depends on the amount
and type of fluid dispensed. In most crop protection fluid
uses (less than 1000 gallons of a clean fluid per year),
the meter will remain accurate for many years without
recalibration. On the other hand, dispensing an abrasive
fluid may require more frequent recalibration.
The 825P / 850P meter is designed to be calibrated with
clean water for safe handling. See "Water Calibration"
section in Appendix - B.
Storage
Store in a cool, dry place. Drain out all fluid that could
freeze in the meter.
