For pH sensors only:
• Temperature measurement
• Impedance measurement (blue wire from the controller):
• Program the control frequency upper and lower limits (refer to the 9500 user manual):
• Glass impedance: 50 Mohm to 500 Mohm
• Reference impedance: 1 to 100 kohm
Calibration
Before calibrating for the first time:
1. Shake the probe gently to remove any air bubbles from underneath the glass bulb.
2. Remove the storage cap and rinse the probe with demineralized water.
