on the right. On the left is shown solution type selected (NaCl) for
mineral/salt (ref. Solution Selection, pg. 14). An overrange condition
will show only [- - - -].
c. TDS key
A press of displays Total Dissolved Solids with units on the right.
This is a display of the concentration of material calculated from
compensated conductivity using the characteristics of a known
material. On the left is shown solution type selected for TDS (ref.
Solution Selection, pg. 14).
3. pH and ORP/Fr Chl Keys
Measurements are made on solution held in the pH/ORP sensor well
(ref. pH and ORP, pg. 42). The protective cap is removed and the sensor
well is filled and rinsed with the sample enough times to completely
replace the pH Sensor Storage Solution.
After use, the pH/ORP sensor well must be refilled with Myron L pH
Sensor Storage Solution, and the protective cap reinstalled securely
(ref. Maintenance of the pH/ORP Sensor, pg. 9 and Cleaning Sensors,
2. pH/ORP, pg. 32).
a. pH Key
A press of displays pH readings. No units are displayed on the
right.
b. ORP/Fr Chl Key
A press of displays Oxidation-Reduction Potential/REDOX
reading in millivolts, “mV” is displayed.
4. CAL/MCLR Key
A press of allows you to enter the calibration mode while
measuring conductivity, TDS or pH. Once in CAL mode, a press of this
key accepts the new value. If no more calibration options follow, the
instrument returns to measuring (ref. Leaving Calibration, pg. 17).
If is held down for about 3 seconds, CAL mode is not entered, but
“SEL” appears to allow Solution Selection (ref. pg. 14) with the Up or
Down keys. As in calibration, the CAL key is now an “accept” key.
While reviewing stored records, the MCLR side of the key is active to
allow clearing records (ref. Clearing a Record/Memory Clear, pg. 23).
