e. If installed electrode is pH, move to step f.
If ORP/mV electrode is installed see Section 9.1 for Probe Selection programming.
f. Temperature Calibration is done at the factory before shipping. For temperature recalibration follow steps
shown in Section 9.8.
g. Factory preset temperature units are
o
C. To change to
o
F, follow instructions in Section 9.9.
h. For pH, perform Two-Point pH calibration as outlined in Section 8.2.
First buffer is pH 7.00 or 6.86 (NIST), second buffer choices are 4.01, 10.00 or 9.18 (NIST). A two-point
calibration must be performed. Three-point calibration is not necessary with the TX100.
