7. CHECK OPERATIONAL PERFORMANCE
7.1 Zero Check
7.1.1 With the probe out of the sample to be tested, depress the pressure sensitive
switch once and then again when EMCEE is displayed.
7.1.2 The display will scroll through the test operation and the new conductivity data
should read “0”. The temperature of the environment will be displayed.
7.1.3 If a number other than “0” is displayed, this probably is an indication that the
probe is contaminated and should be cleaned. (See Paragraph 9. Cleaning
Procedures)
7.2 Over-Range Check – Conductivity is greater than 2K pS/m
7.2.1 Insert the probe into a sample of alcohol (isopropanol), depress the pressure
sensitive switch once and then again when EMCEE is displayed.
7.2.2 At the end of the test period when the LED extinguishes, the display will scroll
through and in lieu of displaying a numerical value for the conductivity the display
will read “OVER” thus indicating that the measurement is over range and the meter is
operating properly.
