1) BNC male connector for single or combination electrode.  Will

accept any pH or ORP electrode with a standard BNC connector.

2) Jack bush connector for reference electrode
3) Banana bush connector for reference electrode

When the electrode attached to the BNC does not have a refer-
ence, connect the reference to one of these sockets (2 choices for
different diameters).

4) Temperature probe socket for use with the HI7669/2W.
5) Reset button.
6) RS 232C socket for serial communication.
7) DC Power Socket (for HI710005 or HI710006).

Electrode and probe connections
For combination pH (or ORP for HI9017 and HI9318) electrodes
(with internal reference) plug the electrode's BNC to the socket pro-
vided (#1).
For electrode with separate reference (see page 58), connect the
measuring electrode's BNC to the BNC socket (#1) and the reference
electrode's jack to the socket provided (#2 or #3).
For temperature measurements and automatic temperature compen-
sation connect the temperature probe to the °C socket (#4).

RESET button
The RESET button (#5) is used when the instrument displays errone-
ous messages due to strong electrical interference or when the
instrument's power supply was disconnected before the meter was
switched off. Press the RESET button and restart the entire operation.
