Since 7.166 Volts is less than 8 Volts (per P175), the output signal is not restricted and would be
7.166 Volts.
If a current output is selected, the output is a milli-amp current where 0 volts corresponds to either
0 mA or 4 mA (as per P177) and 10 volts would translate to 20 mA. Values in between would be
scaled proportionately:
Analog signal resolution: the output is the result of a 16 bit conversion resulting in a resolution of
1 part in 65535 or 10 / 65535 = 0.00015 V.

The Model 370/375 has several pre-programmed scale setpoint applications available at P5100.
Various related setpoint parameters may appear according to which of the standard programs is
chosen. Refer to the chart below for available setpoint operations.

P5100.01
ChecP
Percentage check-weighing. Over/Under tolerances are based on a
percentage of the target weight.
39
P5100.02
Fill
Single Ingredient Fill (Single or Dual-Speed). Allows the use of pre-acts
for dribble feed and compensation for free-fall material. Includes a
selectable ‘learn’ mode.
40
P5100.03
Batch
Batch up to three ingredients. Allows for the use of pre-acts to
compensate for free-fall material. Includes selectable ‘learn’ modes.
41
P5100.04
Dschg
Single Ingredient Discharge (Single or Dual-Speed). Allows the use of
pre-acts for dribble feed and compensation for free-fall material. Includes
a selectable ‘learn’ mode.
43
P5100.05
Both
Single Ingredient Fill and Discharge. Fill large holding vessels and
discharge material in pre-determined amounts. Allows for the use of pre-
acts to compensate for free-fall material. Includes a selectable ‘learn’
mode.
45
P5100.06
ChecA
Absolute check-weighing. Over/Under tolerances are based on discrete
values.
46
P5100.07
Indep
Independent Setpoints. Activation based on specific target values.
Includes selectable reset conditions.
47
P5100.08
Checb
Target Deviation check-weighing. Over/Under tolerances are deviated
from the target weight.

Each program utilizes the three annunciators located to the left of the main display to give a
visual status of the setpoint. A setpoint option board may be installed to allow control of an
external device (see Setpoint Card Connections on page 12).
