The Series BGM Digital Bar Graph Meter is extremely durable and can
replace a wide range of analog meters. The 4-digit display will
significantly reduce the potential for human error in reading by eliminating
errors commonly produced by the viewing angle when reading analog
meters. This series has a key pad that allows for easy access of features
without complex menu structures. With the combined ability to create a
wide range of custom faceplate and the optional NEMA 4X bezel, the
Series BGM can be used in a variety of applications. The LED bar graph
adds a visual indicator of the measured value so that it can be visually
analyzed, preventing accidents or system failures from happening.

FRONT PANEL CONTROLS
PEAK / ^ (SET)
• Press and hold to view peak value
• To reset the peak value - while holding ‘PEAK’, press ‘SETPT/RESET’
momentarily.
• When in the setpoint or menu mode, this button changes the setting for
a parameter or increments the flashing digit.
SETPT / RESET
• Press momentarily to view/set setpoint 1 - see instructions below to set
a setpoint or scaling value.
• Press again momentarily to view/set setpoint 2 - see instructions below
to set a setpoint or scaling value.
• Press again momentarily to return to the operate mode.
• Press while holding ‘PEAK’, ‘VALLEY’ or ‘TARE’ to reset those values.
TARE
• Press momentarily to zero meter display.
• Display offset (TARE) value is stored until power is removed, menu is
entered or TARE is reset.
• To reset the TARE value - while holding ‘TARE’, press ‘SETPT/RESET’
momentarily.
MENU
• Press to enter the menu/scaling mode.
• Press again to exit the menu/scaling mode.
VALLEY / > (STEP)
• Press and hold to view valley value.
• To reset the valley value - while holding ‘VALLEY’, press
‘SETPT/RESET’ momentarily.
• When in the setpoint or menu mode, this button advances to the next
parameter or to the next digit.
