[Note: To exit the calibration mode at this time, press the “Mode”
key. Dual point calibration is complete.]
5. Rinse the pH and ATC/Temp probe in distilled water and
immerse them in the third buffer solution (either 9.18/10.01
or 4.00/4.01). Allow temperature reading to stabilize, then
press “Slope” key to calibrate. The “WAIT” icon will flash until
the unit detects a stable reading. Once the unit calibrates the
third point and the unit will automatically exit the calibration
mode. The three point calibration is complete.
6. The unit calculates and compensates for the pH electrode
slope deviation corresponding to the values of the three
calibration buffers. After calibration, press and hold
“Mea./Eff.” key for about 5 seconds to display the new
electrode efficiency.
Calibration with manual temperature compensation in
the pH‐AUTOLOCK mode
1. Turn the unit on. Press “Clear” key for 2 seconds, all LCD
elements will light up. The meter clears all calibration
values stored in internal memory.
2. Connect the pH electrode to the BNC connector of the
unit, “MAN” icon will light up. “pH” icon and “AUTO” icon
lit up. The “STAND” icon will flash.
3. Rinse the pH probes in distilled water and immerse it in
the first buffer solution (either 7.00 or 6.86). Adjust the
temperature reading to that of the first buffer using the up
or down keys (0.0 to 60.0Ԩ) before pressing the “Stand”
key. Then press and hold the “Stand” key for 5 seconds to
calibrate. The “WAIT” icon will flash until the unit detects a
stable reading. Once the unit calibrates the first point, the
“SLOPE” icon will flash. The unit is ready to be sloped at
the second buffer.
4. Rinse the pH probe in distilled water and immerse it in the
second buffer solution (either 4.00/4.01 or 9.18/10.01),
then press “Slope” key to calibrate. The “WAIT” icon will
flash until the unit detects a stable reading. Once the unit
calibrates the second point, the “SLOPE” icon will flash.
The unit is ready to be sloped at the third buffer.

Calibration with an ATC/Temp probe in the pH NON‐
AUTOLOCK mode
1. Turn the unit on. Press “Clear” key for 2 seconds, all LCD
elements will light up. The meter clears all calibration
values stored in internal memory.
2. Connect the pH electrode to the BNC connector and the
ATC/Temp probe to the ATC/Temp connector of the unit:
“ATC” icon will light up. “pH” icon is on. The “STAND”
icon will flash.
3. Rinse the pH and ATC/Temp probes in distilled water
and immerse them in the first buffer solution (either 7.00
or 6.86). Allow temperature reading to stabilize, then
press and hold “Stand” key for 5 seconds to calibrate.
Once the unit calibrates the first point, the “SLOPE” icon
will flash. The unit is ready to be sloped at the second
buffer.

immerse them in the second buffer solution (either
4.00/4.01 or 9.18/10.01). Allow temperature reading to
stabilize, then press “Slope” key to calibrate. Once the
unit calibrates the second point, the “SLOPE” icon will
flash. The unit is ready to be sloped at the third buffer.
