The Relative mV value is displayed on the first LCD line and the
temperature on the second LCD line.
Using the
keys, date, time, battery status and offset can be
displayed on the third LCD line. If the reading is out of measurement
range, the closest full scale value will be displayed blinking on the
first LCD line.
Error Messages During Measurement
If the mV or temperature exceeds the limits of the sensor, the message
“ELECTRODE OUT OF SPEC” will scroll on the third LCD line. The
temperature will continue to be displayed. If temperature exceeds the
meter specification of 120 ºC, then “120 ºC” will blink on the display.
If interval logging, the message “OUT OF SPEC.” will alternate with the
LOG specific message in both these cases and the Log file will indicate
a “ºC!” next to the data.
In case the temperature sensor is damaged, “BROKEN TEMPERATURE
SENSOR” will be displayed and the temperature will display “25.0”
and the unit tag blinking on the second LCD line. The Log file will
indicate “ºC!!” next to the data.
Relative mV Reading
The RelmV reading can be displayed on the LCD by pressing the
RANGE /
u
key.
The relative mV reading is equal to the difference between the absolute
mV input and the relative mV offset established in the relative mV
calibration.
