Use and Care Manual

NOTE: While checking the MIN/MAX value for "Ex" don’t replace
the probe or you will get an error code. If you don’t plug the probe
into socket before turning the meter on, the error code will also
appear when you check the MIN/MAX value.
NOTE: Low battery power tends to give inaccurate readings,
therefore make sure you have enough power.
Calibration
WARNINGS
• You can exit the calibration procedure without saving the data in
the memory by pressing the "ON/OFF" button before step 4. During
step 4, press the "ON/OFF" button to exit the calibration mode.
• Auto power off is disabled in calibration mode.
• For the highest accuracy, the calibration should be operated at
23°C.
• If the reading is out of 75.3% 0.5% at step 4, this indicates the
calibration has failed. See troubleshooting section below.
1. Turn the meter off and plug the sensor probe into 33% salt bottle.
Press the "ON/OFF + C/F " buttons for more than one second to
enter calibration mode.
2. "32.8%" will flash on the display, when "---.-" is showing on the
display, that means the values are invalid in the calibration process.
After 30 min, the flashing will stop to indicate the procedure is
finished.
3. Move the sensor to 75% salt bottle and press "MN/MX" for more
than one second to enter 75.3% calibration. "75.3%" will flash
on the display.
4. The flashing will stop after 30 minutes, at this point the
entire calibration is completed and the calibration data
has been saved in memory.
