SPECIFICATIONS

Description:

Featuring up to 4 1/2 digits of display, the Squirt-R is a loop powered indicator capable of accepting either linear or square root 4-20 mA inputs. Numeric password protection prevents unauthorized access to the menu. The easy to read menu prompts make the Squirt-R so easy to program that you will feel comfortable programming it without the use of a manual.

DISPLAY:

Display: (selectable decimal)

3.5 or 4.5 Digits (selectable), 0.35" High, Display updates once every two seconds.

Rate Descriptors: /SEC, /MIN, /HR or "blank" Units (totalizer) Descriptors: GAL, LIT, FT3, M3, "blank" Low Battery Error Detection: "BAT" descriptor & flashing

DEFINITIONS

ent code

: (enter code) This prompt will only appear if the panel lock is ON. Enter the password code to enter the program menu. Press the ↑ key to increment each digit. Press the ← key to step to the next digit to the left. Press the E key to enter the 4 digit code. If the entered code is correct, the display will advance to the next menu prompt (CLr tot). If incorrect, the display will return to the run mode.

clr tot

: (clear total) Clears (resets) the totalizer. Press the E key to clear the total and return to

the run mode. Press the M key to skip and advance to the next menu selection.

: (3.5 or 4.5 digits) Choose between 3.5 or 4.5 digit rate display. Press the ↑ key to step to

the desired choice. Press the E key to enter the displayed choice.

dec loc

: (Decimal Location) Sets the decimal location for the display and the

rate lo

& settings. Press the ← key to move the decimal. Press the E key to enter the displayed decimal location.

tot desc

: (totalizer descriptor) This allows you to display one of the available descriptors on the display (GAL, LIT, FT3, M3 or "blank"). Press the ↑ key to select the descriptor. Press the E key to enter the selected descriptor.

rat desc

: (ratemeter descriptor) Sets the rate descriptor. Choose rate per hour, minutes, seconds or "blank". Press the ↑ key to step to the desired choice. Press the E key to enter the displayed descriptor.

rate hi

input

: (input type) Choose between linear (

lin

) or Square Root Extraction (

SQ.u

) . Press the ↑ to

step to the desired input type. Press the E key to enter the displayed choice.

rate lo

: (rate low) Sets the low setting for the 4-20 mA analog input. Key in the low rate value which corresponds to the 4mA input. Press the ↑ key to increment each digit. Press the ← key to step to the next digit to the left. Press the E key to enter the displayed rate lo value.

rate hi

: (rate high) Sets the high setting for the 4-20 mA analog input. Key in the high rate value which corresponds to the 20mA input. Press the ↑ key to increment each digit. Press the ← key to step to the next digit to the left. Press the E key to enter the displayed rate hi value.

lo cut

: (low cutoff) Percent of input span (0.1 to 9.9) below which all inputs will assume the rate

lo value. (With

LoCut

set at 9.9, and

rAteLo

set to 0, all inputs below 5.6mA will read 0) CALCULATION EXAMPLE: Given: Cutoff desired at 9.9% span Compute: mA corresponding to 9.9% = ((9.9%*16mA)/100%) + 4mA = 5.6mA

Battery Replacement

Suggested Battery: Panasonic BR2330

The polarity of the battery must be correct. Plus (+) must be on top as signified on the conductor arm.

Note: The unit must be powered by the loop and reinitialized immediately after battery replacement to prevent early battery discharge. All menu items must be re-entered and the unit must be recalibrated.
