SPECIFICATIONS

Description:

Featuring up to 4 1/2 digits of rate and 8 digits of total,
the Squirt is a loop powered indicator capable of accept­ing either linear or square root 4-20 mA inputs. An
isolated scaled pulse output is available for hook up to a
remote totalizer. Numeric password protection prevents
unauthorized access to menu. The easy to read menu
prompts make the Squirt so easy to program that you will
feel comfortable programming it without the use of a
manual.

Specifications:

display

Under/Over range Indication: Display flashes when out

of range

INPUTS:

Signal Input:

Full Scale Range: 4 to 20 mA DC
Loop Voltage Drop: 6 Volts Maximum
Reverse Polarity Protected
Over Current Protection to 60 mA
16 Bit resolution; 1 sample every 2 seconds
Low Cutoff supplied to inhibit indications at low flow
rates.

Reset Input: (contact closure)

Internal Pullup Resistor: 100 kΩ to +3 VDC
High (logic 1): Open or 3-30 VDC
Low (logic 0): Less Than .5 VDC
Minimum On : 25 msec
NOTE: The reset input is not protected by the pass-

word or jumper lockout.

CAUTION: Sustained contact closures will shorten

battery life.

PULSE OUTPUT:

The pulse output advances with the least significant digit

of the totalizer.

Type: Opto-isolated open collector transistor.

Max. voltage (off state): 30 VDC
Current (on state): 5 mA @ .9 V drop, .1mA @ .7 drop
Pulse Duration: 15 msec
Pulse Output Rate: 25 CPS max.

Pulse output divider: User selectable: ÷1, ÷10, ÷100 or

off

ENVIRONMENTAL:

OPERATING TEMPERATURE

-4°F (-20°C) to + 158°F (70°C)
Extended Temp: -22°F (-30°C) to + 158°F (70°C)

HUMIDITY

0 - 90% Noncondensing

ACCURACY: (Rate @ 20°C)

0.1% Full Scale Resolution, ±1 count
Temperature Drift:

50 ppm/°C Typical
200 ppm/°C Worst Case

LOCKOUT:

Password: Unauthorized menu changes can be pre-

vented by entering a user selectable password (5 digit
number).

Jumper: An internal jumper shunt is provided for applica-

tions requiring a "sealed" menu and totalizer lockout.
Install the jumper to enable the lock. (see Typical Wir­ing, Pg. 2)
