  • Page 12 2.3.2 Switching Between PT100 & PT1000 Temperature Sensors The Alpha pH 600 transmitter supports both Pt100 & Pt1000 (2-wire or 3-wire) temperature sensors. The default factory setting is Pt100. If you need to use Pt1000 temperature sensor, you have to change the jumper setting (J201) as described below.
  • Page 13 2.3.3 Connecting pH/ORP Electrode If the pH/ORP electrode has a BNC connector, remove the BNC connector from the cable. NOTE: Oakton Instruments offers an optional ‘BNC to Spade Lug adapter’ (Order code: 05994-90) that can be used with pH/ORP electrode without removing the BNC connector. Strip the insulation of the cable so that the bare wires are exposed enough for connection as shown in Figure 3.

  • Page 21: Calibration Mode

    CALIBRATION MODE Preparing the Transmitter & Electrode for Calibration Before starting calibration, make sure that the pH Transmitter is in appropriate measurement mode (pH or ORP). When the Transmitter is powered on, it starts up with the measurement mode last used. For example, if the pH Transmitter is powered off in ORP measurement mode, it starts up in ORP mode when it is powered on.

    READY °C • To exit Calibration mode at any time press ▲ and ▼ keys simultaneously (Escape). • The calibration is always carried out in the units of HOLD measurement (pH or mV), selected in setup mode pH Calibration The pH Transmitter is capable of calibration of up to 2 points using USA or NIST pH buffer standards.
  • Page 23: Point Calibration

    From pH measurement mode press CAL key to enter calibration mode as described in section 4.2. The LCD shows ‘CAL PH’. Press ENT key to begin calibration. Place the electrode in pH 7.00 buffer. Immerse the temperature probe in the buffer solution if ATC mode is enabled. Immerse the potential matching pin in the buffer if symmetrical mode is enabled.
