1.3 CONNECTORS

Figure 4 illustrates the Top View showing connectors
of the AP meter.
Note that the meter is waterproof only when the
blue rubber plugs and/or the appropriate ATC
probe are used. If the meter is totally submersed,
water may enter the BNC connector. If necessary, dry
the connector to avoid corrosion. Also, If an AC
adapter is connected, the meter is not waterproof.

The AC jack is used to connect an optional power
adapter. If an AC adapter is not used, Seal the jack
with the blue rubber plug to maintain a waterproof
state. An AC adapter prevents battery drain by
removing the battery from the circuit.
For pH, mV, R.mV, and Ion measurement, attach
combination electrodes with BNC connectors directly
to the middle BNC jack on the meter. Non-
combination (half cell) electrodes can be used with
appropriate adapters sold separately.
For best results, automatic temperature compensation
(ATC) is recommended. Insert the accumet waterproof
ATC connector into the ATC jack. Insert the attached
blue rubber plug if an ATC probe is not used to
maintain a waterproof state.
