Option Function Description
READY Stabilization lock Sets the stabilization lock to on or off.
• The "READY" icon shows when an endpoint occurs and the stabilization
lock is set to on.
• After stabilization, the display locks the value and the meter ignores slight
changes in the measurement of pH, conductivity or TDS.
• Sets the stabilization lock to off during titrations or slight change detection.
The display automatically unlocks after a significant measurement change
is found.
ºC ºF Temperature
display Sets the temperature unit to ºC or ºF.
Snd Sound options Sets the sound alerts to on or off. Three sounds tell the user about different
functions:
• One beep: Stabilization occurred with the stabilization lock on.
• Two beeps: An error occurred. The error code shows on the display. Refer
to Error codes on page 18.
• Three beeps: Measurement stability in calibration mode, regardless of the
stabilization lock setting.
oFF Automatic
shutdown Sets shutdown parameters from 1 minute to 000 minutes (continuous power).
The meter beeps 1 minute before shutdown. Make sure to power cycle for the
automatic shutdown to occur. Automatic shutdown disables during: data
logging, Bluetooth
™ transfers and when connected to the USB port.
CLr ALL
CAL Clear calibration
points Erases all calibration points in storage. Calibrate the meter again. 1
1 This does not erase calibration data for an ISFET probe.
4. Push ENTER to keep the changes and go back to setup mode.
Note: To exit and not keep the changes, push SETUP.
Operation
Override an error
The user can override some errors (e.g., poor electrode condition) until a replacement electrode is
ordered and received.
Note: It is not possible to override all errors. The manufacturer does not recommend that the user override error
codes. Contact technical support to override error codes.
To cancel or override an error:
1. Find the cause of the error. Refer to Error codes on page 18. If possible, push SETUP or pH,
COND, TDS or SAL to cancel the calibration or other error.
2. To override the error, do not complete step 1 . Instead, push ENTER.
3. Use the arrow keys until "YES" shows.
4. Push ENTER.
Set the pH operations
Set the calibration alarm, the pH resolution, the calibration points and the calibration methods.
Complete the operations in order.
1. Set the power to on.
2. Push SETUP, then pH.
3. Use the arrow keys to select an option, then push ENTER:
