Power Supply:
Battery – 1 D Cell Normally NiMH Rechargable
Capacity >7000mAH. May be fitted with Primary
cell – Duracell or equivalent for higher Capacity and /
or longer shelf / standby life.
Power Supply/Battery Life:

Mounting the System
The system should be attached to a secure and stable structure with good visibility of the
display. Securing cylindrical body with a Jubilee® clip is an effective method.
The 4 Digit Subsea Display (not dual), may also be mounted within a Remote Actuator
Assembly, that provides a facility for switching the zero display, scaling and units functions.
Zetechtics Part No: 023-14-16-002.
