Part 8 Calibration
8.1 Getting Started
Before pH and temperature calibration is possible, some preparation is necessary. First, make sure you are in
the proper measurement mode. The measurement mode is shown on the display in the upper right corner
“pH” for pH and “mV” for ORP or other mV sensors.
Ensure the sensor is connected to the transmitter as shown in Part 5.1.
Always use fresh buer solutions when calibrating. Check expiration date on buer package.
If possible, use deionized water to rinse electrode before calibration and between buers.
For temperature calibration, make sure the temperature sensor wires are connected as shown in FIG 5.1. If
no temperature sensor is connected, the transmitter will default to read 25.0 degrees C or 77.0 degrees F.
8.2 2-Point pH Calibration
The TX100 performs two-point calibrations using preprogrammed buer choices. No mV calibration is re-
quired. See Figure 8.1 for calibration programming.
