b. 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. 9).

3. pH Key (TPH1 & TH1)

Measurements are made on the solution contained in the pH sensor

well (ref. pH Measurement, pg. 29). The protective cap is removed,

and the sensor well is lled and rinsed with the sample enough times to

completely replace the pH Sensor Storage Solution.

After use, the pH sensor well must be relled with Myron L pH Sensor

Storage Solution, and the protective cap reinstalled securely (ref.

Maintenance of the pH Sensor, pg. 8 and pH, pg. 20).

A press of displays pH readings. No units are 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. 11).

If is held down for 3 seconds, CAL mode is not entered, but

“SEL” appears to allow Solution Selection (ref. pg. 9) with the Up or

Down keys. As in calibration, the CAL key becomes 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. 16).

5. UP or DOWN Keys

While measuring in any parameter, the or keys activate

the Memory Store and Memory Recall functions.

While in CAL mode, the keys step or scroll the displayed value up or

down. A single press steps the display and holding either key scrolls the

value rapidly.

While in Memory Recall, these keys scroll the display up and down

through the stack of records (ref. Memory Recall, pg. 16).
