• Sensor O‑Rings must be lubricated with the supplied grease prior to installation.
• HI769819X probes have 2 or 3 sensor connectors sockets identified with color‑coded triangles:
• Connector 1 (red): For either pH/ORP, pH sensor
• Connector 2 (white): For dissolved oxygen sensor (HI98194, HI98196 only)
• Connector 3 (blue): For EC sensor (HI98194, HI98195 only)
• Position the connector key towards the center of the probe, make sure the connector is seated
correctly (the sensor will no longer move freely) before tightening the locking threads.
• To protect the sensors, screw the protective shield onto the probe body.
• With the meter off, connect the probe to the instrument input on the top of the meter. Align the
pins and key then push the plug into the socket and tighten the thread.
• Turn the meter on by pressing the On/Off key. The meter will automatically recognize the probe
and the installed sensors and identify them on the probe status screen.
• Press Measure to view the measurement screen.
