    4. Scanning Probe Connector. Electrical connection for the optional Scanning Probe. NOTE: Connect the Scanning Probe before applying power to the 2H. Failure to do so will result in the lack of operation of Scanning Probe’s display. If this occurs, simply turn off the power to the unit and restart the system.

    The Selector Valve, the Scanning Probe connector, and the two barbed fittings are discussed later. SCANNING PROBE CONNECTIONS If using the 2H with the Scanning Probe, connect the probe’s electrical connector to the 12-pin connector on the front panel of the 2H before applying power to the photometer. Otherwise, the display on the Scanning Probe will not function.

    CAUTION: The 2H should always be positioned so that the Power Switch, located on the rear panel, is readily accessible in the event the unit needs to be powered off quickly. The Power Connector accepts the female end of the Power Cord that comes with the unit. The internal power supply is a universal supply that can operate at either 50 or 60 Hz and with any voltage from 90 to 240 volts, for use in virtually all countries.

    If the Scanning Probe is being used, connect it to the Scanning Probe Connector and the Downstream Port. Verify that the Selector Valve is in the CLEAR position. Apply power to the 2H by setting the Power Switch to the 1 (On) position. The following events will occur: 1. The display will show “8.8.8.8.8.”...
