WARNING
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. At
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 ash on the display, when "---.-" is showing on the display,
that means the values are invalid in the calibration process. After 30
min, the ashing will stop to indicate the procedure is nished.
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 ash
on the display.
4. The ashing will stop after 30 minutes, at this point the entire
calibration is completed and the calibration data has been
saved in memory.
