4 Introduction
1.3 Overview
The instruments are specifically designed for computing & displaying totals from flowmeters
with pulse or frequency outputs. They are battery powered or can be powered by an external
8~24Vdc regulated or I.S. certified supply.
The instrument will display Resettable Total and an Accumulated Total in engineering units as
programmed by the user. Simple PIN protected flow chart programming with English prompts
guide you through the programming routine greatly reducing the need to refer to the manual.
Special Features
Standard : PIN Protection. Amplified non-scaled repeater or scaleable pulse output.
: NPN/PNP selectable pulse output.
Optional : Display backlighting (needs external dc power for this option to illuminate).
: Intrinsic Safety Certification to IECEx scheme and ATEX directive.
Environments
The instrument is designed to suit harsh indoor and outdoor industrial and marine
environments. The robust housing is weatherproof to IP676 / IP67 standards, UV resistant,
glass reinforced nylon with stainless steel screws & viton O-ring seals.
Installation
Specifically engineered to be directly mounted on a variety of flowmeters, wall, surface or pipe
mounted in the field or control room. Various mounting kits are available. The instrument is
self powered using one 3.6Vdc lithium battery or I.S. battery pack, the pulse output option
requires 8~24Vdc.

2. OPERATION
2.1 Resettable Total
Pressing the RESET key will cause the large 5 digit total to reset to zero. The reset function is
possible at any time during counting.
2.2 Accumulative Total
There are 8 digits in the accumulative total display, these can only be reset in the program
mode or can be protected by enabling the PIN protection feature at the front end of program
mode.

2.4 Battery replacement
The instrument draws very little power and will run for many years* without the need to
replace the battery. A battery condition indicator on the LCD display will appear when the
battery is low, if the low battery is not replaced the programmed detail & totals will be lost.
When changing the battery a small capacitor within the instrument will maintain the
programmed detail & totals in memory for up to 10 seconds providing sufficient time for the
battery change to take place. Changing the battery whilst flow is taking place could cause loss
of the programmed detail. It is advisable to record program details prior to battery change.
* The battery can last 7~10 years depending on application & environment.
2.5 Processor reset button
Should the instrument be corrupted by an electrical hit the processor can be reset by pressing
the black re-boot button located above the red DIP switch block on the input interface board
(refer page 10). This procedure does not effect totals or programmed data.
Full LCD display test feature illuminates all
characters and script text displays for 5
seconds when entering the program mode.
The 5 digit Total display is front panel
resettable and can be programmed for
up to 3 decimal places.
The 8 digit Accumulative Total display
can be programmed for up to 3 decimal
places. Reset is only possible when in
the program mode which can be PIN
protected for security.
Engineering units are selected during
the initial programming routine.
Battery condition indicator shows only
when battery is low, battery life can last
up to 7~10 years.
FUNCTION IN OPERATING MODE
Resets the 5 digit resettable
total display to zero.
Resets the 8 digit accumulativ e
total display to zero. Resets internal K-f actor
(scale f actor) to zero
1. Pressing the Program & Reset keys f or 5
seconds enters y ou into the program mode.
2. Display s model & software rev ision No.
1. Each press steps you through each lev el of
the program chart.
2. Holding f or 3 seconds f ast tracks to the END
of the program f rom any program lev el.
Selects the digit to be set, the selected digit
will be “f lashing ” indicating that it can be
incremented.
Increments the selected digit each time
that it is pressed.
