Field Reference Guide—pH Manager
Keep with pH System and refer to daily.
(Refer to Operating Instruction Manual for complete instructions)
PRIOR TO MAPPING: PERFORM ROUTINE DAILY
MAINTENANCE
3. In Manual Mode test each function
(washing, raising and lowering):
1. Inspect unit for loose
or missing bolts, other
obvious problems
4. Raise and lower sampling shoe—check scraper for
appropriate contact:
2. Are sampling shoe and
trough completely clean of
soil?
5. Inspect prox sensor light during manual cycling:
Adjust hydraulic flow so cycling time is 1.5-2 seconds
6. Raise sampling shoe—check for ¼” to ½” clearance
between electrodes and trough; make sure this is where
the shoe will stop in automatic mode (see prox sensor
adjustment section in Operating Instructions)
7. Operate wash jets and check alignment; does water
bubble out of top when electrodes are removed?
9. Calibrate electrodes
8. Raise unit and drive slowly in semi-circle with unit cycling
to check automated functions
Insert electrodes into holder and fingertighten set screws. Follow menu
prompts to “pH Setup”. The instrument
will prompt for the electrodes to be
inserted into pH buffer 4 solution; Slide
pH 4 buffer solution container onto
electrode holder. Press 1 to continue
with calibration or 2 to exit. Repeat with
pH 7 buffer solution.
