Measuring the temperature

The temperature measurement is absolutely essential for a reproducible ORP
measurement.
You have the following options to measure the temperature:
• Measurement with an external temperature sensor.
• Manual determination and input of the temperature.
The measuring instrument recognizes whether a suitable sensor is connected
and automatically switches on the temperature measurement.
Which type of temperature measurement is active is indicated by the tempera-
ture display and the [TP] status indicator:
Temperature Resolution of the
sensor
yes 0.1
- 1 °C
If the measurement is made without a temperature sensor, proceed as follows:
1. Measure the current temperature of the test sample.
2. Set the temperature value with <><>.

Calibration

ORP electrodes are not calibrated. You can, however, check ORP electrodes
using a test solution.
