Standard Scaling
Standard display mode selected and
scaled so bar increases as input signal
increases from Low to Hi.
Halfway Zero Point
Center point display mode selected and
scaled, so the bar increases upwards or
downwards from the center point, for sig-
nals that are greater or less than half the
calibrated full scale range respectively.
When the input is equal to half the full
scale range, only the center segment will
be on.
Inverse Scaling
Standard display mode selected and
scaled so the bar increases as the
input signal decreases from Hi to Low.
Bipolar Center Zero
Center point display mode selected and
scaled, so the bar increases upward from
zero, for increasing positive inputs and
downward from zero for increasing neg-
ative inputs. When the input is zero, only
the center segment will be on.

Display with 4 Set Points
With Standard display or Center point
mode selected, the setpoints are
indicated by an
ON
segment outside
the bar display area and by an
OFF
segment inside the bar display area.
Horizontal or Reverse Mounting
Meters can be mounted horizontally
in the panel and for those applica-
tions that require an opposite growth
of the bar, the meter can be verti-
cally or horizontally mounted upside
down

Mode 3 Hysteresis Band between SP1 & SP2
This mode enables the Hysteresis function. In order for Hysteresis to function, SP2 must be set to a value greater than SP1, and SP2 should
be selected as High (h) Setpoint (See page 7). When these conditions are met, and Mode 3 is selected, then a Hysteresis band is created
for the SP1 relay, with the upper limit of SP2 and the lower limit of SP1. SP2 relay continues to operate
normally.
•For a tank filling application SP1 is set to a Low (L) Setpoint. SP1 relay can control a pump that fills
the tank. With Mode 3 selected, SP1 relay activates for inputs less than the SP1 level. Once activated,
SP1 relay will stay ON until the tank is filled to the SP2 level.
•For a tank emptying application SP1 is set to a High (h) Setpoint. SP1 can control a pump that emp-
ties the tank. With Mode 3 selected, SP1 relay activates for inputs greater than the SP2 level. Once
activated, SP1 relay will stay ON until the tank is emptied to the SP1 level.
