1.2 Specifications

Display : 5 digit resettable LCD totaliser 7.5mm ( 0.3") high with second
line 8 digit accumulative total display & text 3.6mm ( 0.15") high.
3 programmable decimal points with both display lines.
Signal Inputs : Universal pulse-frequency input compatible with Reed switch,
Hall effect, Coil-sine (20mV P-P min.), Voltage or current pulse &
Namur proximity detectors. Maximum input frequency is 5Khz for
coils, 2.5Khz for Hall effect & current pulse inputs, 2Khz for voltage
pulse devices & 500Hz for a Namur proximity sensor.
Powering : 3.6Vdc Ultra Lithium battery or I.S. battery pack supplied, life
expectancy can be up to 7~10 years. Battery life reduces when
connected with a coil input from turbine flowmeters. The
instrument may be externally powered from a regulated 8~24Vdc
supply (see page 14 for special instructions regarding ghosting).
Pulse output : Scaleable or non-scaleable NPN-PNP selectable field effect output
transistor. Non scaleable pulse is particularly suitable for pre-
amplifying pick-off coil inputs from turbine meters ( 5Khz. Ma x.).
The scaleable pulse output has a fixed pulse width of 60ms and
therefore has a frequency limit of 8hz . Both pulse outputs have a
50mA maximum drive capability.
Physical : A) IP66/67 high impact, glass reinforced nylon enclosure.
B) Self drill cable gland entry at base & rear of the enclosure.
C) Overall 85mm diameter x 45mm deep x 175g (0.4lb).
D) Operating temperature -20ºC ~ +80ºC ( -4ºF ~ +176ºF).
Configuration
Functions : Accumulated & Resettable totals, pre-amplifier pulse output & a
scaleable pulse output. Low battery indication.
Configuration : Flow chart entry of data with English text prompts.
User selectable 4 digit PIN number program protection.
Programmable engineering units, decimal points and K-factors.
All programmed data protected with the battery.
K-factor range : Entered as pulses / litre, gallon, lb etc. Programmable range is
0.001~9,999,999.999 with a floating decimal point during K-factor
(scale factor) entry.
Pulse output range : Entered as engineering units/pulse. Range is 0.1~9999.9
units/pulse.
Engineering units : Selectable Ltr, Gal, m3, kgs, lbs, MLtr & Mgal or no units of display.
