DOX8HS (Style B) Submersion Type Holder
The holder holds the sensor at an angle of 45°. Consequently, bubbles will not stick to the sensor
the tip. Any pollutants in the SUM can be automatically cleaned off at regular intervals using a jet-
spray water (air) cleaner.

2.2.3 Installing the Sensor in the Holder
For details on how to install the sensor in the holder, see the appropriate instruction manual for
each holder.
CAUTION
Do not contaminate or wet the tip of the sensor cable when assembling the sensor.
If you will not begin wiring the sensor cable immediately, take the protective measures necessary
to prevent the assembly from being damaged.
2.3 Connecting the Sensor Cable
Sensor cable to connect to DO70G is defined by the model of converter to be used.
For information on sensor cable to connect DO70G to DO402G, refer to the user’s manual for
DO402G Dissolved Oxygen Converter instruction manual (IM 12J05D02-01E) or the one for
DOX10 (IM 12J05S01-01E).
For the connection with FLXA402, read a user’s manual for FLXA402 4-Wire Converter
(IM12A01F01-02EN) and select an appropriate sensor cable.
NOTE
A jumper cable is placed to connect converter terminals 13 and 17.
When a standard optical sensor (DO70G) is to be connected, the cable is not used, so
disconnect it.
