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.

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 or 4
: (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 for ratemeter) Sets the decimal location for the ratemeter and the
rate lo
&
rate hi
settings. Press the ← key to move the decimal. Press the E key to enter
the displayed decimal location.
tdec
: (totalizer decimal) Sets the decimal location for the totalizer. The totalizer decimal is not a
dummy decimal and will scale the totalizer display accordingly. (i.e. if the tdec is set in the
tenths position (1234567.8), 100 will be displayed as 100.0). The location of the decimal point
allows for greater resolution of both the totalizer display and the pulse output. The pulse
output advances at a rate dependent on the least significant digit of the totalizer. The totalizer
decimal location is restricted to a maximum of 4 places (1234.5678).
tot desc
: (totalizer descriptor) This allows you to illuminate 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/scaling) Sets the rate readout. Choose rate per hour, minutes,
seconds or "blank" (when no descriptor is selected the unit assumes that the rate lo and rate
hi are entered in units per second). Press the ↑ key to step to the desired choice. Press the E
key to enter the illuminated descriptor.
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. (i.e. With
lo cut
set at 9.9 and
rate lo
set at 0, all inputs below 5.6 mA will read 0)
