Changing the CAL Factor
• Hold button 3until the display only shows CAL and number.
• Press 3repeatedly until you reach the desired number.
NOTE: Number will step up to 19, then back to zero.
• Press 2to return to normal operating mode.
Calibration Procedure
A) Set CAL factor to 10.
Hold button 3for three seconds. Press 3again until the number 10
shows below “CAL” (NOTE: If you go past 10 keep pressing 3because
the number will return to 0 after passing 19).
Press 2to get back to normal operating mode.
NOTE: If your fluid is listed on Table 1, use that number in step A above
in place of 10.
B) Prime pump and meter by dispensing 2 - 3 gallons of fluid back
into the bulk tank.
With the outlet valve closed and the pump still running, reset the
meter to 0.00.
C) Fill the Proving Can exactly to the 5.0 gallon line.
Focus on the Proving Can, do not look at the meter at this point. Keep the
hose end nozzle wide open as long as possible for best accuracy.
D) Adjust Meter CAL Factor.
• If meter reads high, increase the CAL factor. Each CAL # changes the
accuracy by about 1%. For a 5 gallon proving can, 1% = 0.05 gallons.
• If 5.10 is displayed, this is 2% over 5.00; the CAL factor should be
changed to CAL 12.
• If the meter reads low, lower the CAL factor. For example, if 4.90 is
displayed, it is 2% less than 5.00, so the CAL factor should be set to 8.
• When finished with the CAL factor procedure, press 2to return
to normal mode and to reset the meter to 0.00. The meter is now
calibrated and ready to use.
Calibration Procedure Using the CAL Factor

| 820,825, 850 DIGITAL PULSE OUTPUT METERS INSTALLATION AND OPERATION MANUAL
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). 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.
3. Remove old batteries and insert new batteries, making sure battery
polarity is correct, or meter damage could occur.
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 12 for correct replacement part information
before ordering.
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). 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) 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.
6. Reassemble meter.
CALIBRATION NOTE: Over time, the chamber inside the meter will wear,
requiring the meter to be recalibrated 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 825 / 850 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.
