Preparation
2.2 Connecting the Sensor Cable
Connect the sensor cable.
CAUTION
Connect the sensor cable in a place free from moisture.
When connecting the sensor cable, tighten by turning only the silver locknut, do
not turn the cable or waterproof cover. Also take care not wet or contaminate the
connector.
Sensors for the PH81 or PH82 meters can be connected. When used in conjunction
with the PH72 meter, however, water resistance is not guaranteed. This is due to the
different construction of the connector cover.

(1) Pull the waterproof cover along
the sensor cable away from the
connector to expose the locknut.
(2) Connect the connector to the
meter body*. Then tighten firmly
by turning only the locknut.
* Align the slots of the sensor cable
connector with the posts of the
connector on the meter.
(3) Move the waterproof cover
toward the connector until it
contacts with the O-ring* on the
meter body.
* Make sure that the O-ring is free of
foreign material.

Note:
It is recommended that the sensor be kept connected to the meter to avoid
contamination of the connectors.
2.3 Setting the Date and Time
After installing the batteries, set the date and time. Note that if the power is turned
off before completing minute setting, start with the date setting when you turn on the
power next time. By replacing the batteries, the date setting is not affected but the
time setting is. So the time must be reset.
Note:
If a sensor cable is not connected to the meter, fluctuating readings or an error message
may appear. Before pressing
POWER
key, make sure that a sensor has been
connected.
