ESCRIPTION
The Dual 4 Digit Subsea Display System is capable of operating as both a quadrature counter
display and a display for a strain gauge derived input such as torque,. The system displays turns
and torque simultaneously without the need for any re-configuration or switching of displays.
The default factory set condition is that the strain gauge input (torque) is displayed at the top
and the count display is at the bottom 4 digit display.
The operational modes described in the previous sections for the Strain Gauge and Quadrature
Counter systems are all applicable to the Dual 4 Digit subsea Display.
The unit is therefore particularly suitable for use with a Torque Tool, where readings of “Number
of Turns” and “Applied Torque” are required.

ONTROLS
The display consists of two 4 digit displays enclosed within one display housing. Each display has
two magnet operated reed switches, one at the left of the front and one at the front right side.
Therefore the dual display has two switches to the left side and two to the right.
Left Reed Switches : Either switch will change the units of the top display showing strain gauge
input (Torque) between Nm and lb.ft.
Right Reed Switches : Either switch will simultaneously “Tare” the top display (Torque) and
zero the count of the bottom 4 digit display.

WHAT DOES IT MEAN
?
Description Cause
The display is illuminated constantly
No option links are fitted or light sensor
disabled.
The display is only illuminated when a light is
shone on the unit
The Subsea Display System is set to only
operate when illuminated, option link A is
fitted or light sensor enabled.
The display is not illuminated at all
There is insufficient light shining on the
unit when option link A fitted / light sensor
enabled.
OR
The battery is completely flat.
The display shows ErHi
The input value is above that set as
maximum or there is a sensor cabling /
connector fault.
The display shows ErLo
The input value is below that set as
minimum or there is a sensor cabling /
connector fault.
The display is on continually except for a brief
flicker every six seconds
Option link A is fitted / light sensor is
enabled (the unit turns off the display to test
the ambient light level).
The display is on continually except for two brief
periods every six seconds
The battery is nearly discharged
