HELP!! How to set a Milwaukee SMS122 calibration properly?

[jeemann99]

I purchased a used Milwaukee SMS122 PH unit and it did not come with a manual. My question is calibration.

Steps:

1. Turn off unit
2. Put probe into PH Fluid and set to 7.0
3. Turn off probe
4. Place probe into effluent container
5. turn on probe
6. keep effluent at approx. 6.3 - 6.5

I am unsure about the on and off.......


Thanks in advance
Garrick

Won't help much now but I just ordered a new one today. should have it in a couple of days, if you want I can make you a copy of the manual.

Garrick, you leave it on, you put the probe in the 7.0 solution. If your reading doesn't go to 7.0, you have to adjust it up or down, there's a hole on the front of the controller, says "cal", need a small screwdriver to make this adjutment. With the probe in the calibrating solution, adjust if necessary to 7.0.
