7. Prox sensor: The prox sensor communicates the position of the sampler assembly to the

external controller for automatic cycling functions. Adjust sensor to 1/4”- 3/8” (6-9 mm) gap.

Cycle unit manually to insure that this gap is maintained throughout cycling range. Red LED

light should light whenever prox sensor is near metal and not light when away from metal. To

view LED light, shade ambient light from prox sensor and cycle sampler assembly manually.

Be careful to not strike or damage prox sensor face. Adjust prox sensor height with sampler

shoe completely raised. Adjust the prox sensor so it barely clears the lower part of the sensor

plate when sampler is completely raised. It may be necessary to reposition the electrode

holder after adjusting prox sensor; see step 2 above.

Installing electrodes

pH Electrode Calibration Procedure: perform daily

1. Thoroughly wash the electrodes and electrode holder; wash for 30-60 seconds before

calibrating and between each solution.

2. Wipe the electrode holder dry; gently dry the electrode holder face and electrodes with a paper

towel. Do not touch the face or dome of the electrode.

3. Turn on the Veris Instrument.

4. Enter menu option 2) pH Setup:

5. Enter menu option 1) Calibrate ISE’s:

6. Enter menu option 1) Continue with calibration.
