H. Set the mode selector switch to SET-UP and change the calibration number using the INC/
DEC switch. Return the mode selector to OPERATE and TASC should display the amount
actually measured. The calibration is complete.
IF IT IS NOT CONVENIENT TO CONDUCT AN ACTUAL CATCH TEST,
FIELD EXPERIENCE WILL ALLOW YOU TO FINE TUNE THE FLOW
METER CALIBRATION NUMBER. IF CHANNEL L IS APPLYING TOO
MUCH, DECREASE THE CALIBRATION NUMBER BY THE SAME
PERCENTAGE AS THE OVER APPLICATION. IF CHANNEL L IS
APPLYING TOO LITTLE (YOU HAVE MATERIAL LEFT OVER) IN-
CREASE THE CALIBRATION NUMBER BY THE SAME PERCENT-
AGE AS THE UNDER APPLICATION.
CALIBRATING WITH WATER WILL BE SUFFICIENT FOR MOST
MATERIALS; HOWEVER, FACTORS SUCH AS VISCOSITY AND
DENSITY CAN AFFECT THE CALIBRATION. FOR MATERIALS THAT
ARE MUCH DIFFERENT THAN WATER, THE CHANNEL SHOULD BE
CALIBRATED WITH THE MATERIAL TO BE APPLIED.
6.10 CALIBRATING CHANNELS 1,2 AND 3 (not applicable to 6200)
Channels 1,2 or 3 can be either liquid injection channels or granular co-applicator channels. The calibra-
tion methods are similar. It is necessary for you to be able to catch and measure the discharge from each
channel.
6.10.1 CALIBRATING MID-TECH® INJECTION PUMPS
If you are using a MID-TECH ® injection pump, use the following calibration numbers to get started. (Be
sure the channel is set to peristaltic drive, section 6.5 of the manual.)
The following values are typical PC#’s you can expect to see on MID-TECH injection pumps after
performing the field calibration procedure. If your pump calibration number differs from the typical
range, check the calibration. Use these numbers for your initial pump calibration numbers, before
conducting the actual prime or pump calibration procedure.
