The SERIES SPPM Smart Programmable Panel Meter is a congurable, full color
display that can be used in a variety of applications. Utilizing a USB connection, the
panel meter can be congured with downloadable software, using any computer
running Windows
features remarkable graphics that can easily be customized to read and/or graph
pressure, temperature, humidity, gas concentration, or many other parameters. Up to
two transmitters or transducers can feed the panel meter’s user scalable inputs. The
Series SPPM includes a gasket and mounting clip for quick installation into a panel.

Series SPPM features two voltage inputs that can be programmed independently.
With the downloadable software, the user can scale the two voltages to create eight
different voltage ranges. The software is programmed to use the smallest range
possible because the smallest voltage range offers the highest resolution. The eight
possible voltage ranges and their corresponding resolutions can be found in the
Table 1.

USB Connection
A USB cable is required for customization of the Series SPPM. When connected to a
PC’s USB port, the display is powered by the PC.
CAUTION
NOTICE
Pin Connection
The DIL IDC socket is an alternative to using the screw terminals. This connection
can also be utilized for data busses and alarm outputs. See Figure 3 for the pin
layout.
For safety reasons, the meter should be isolated from both the
supply and signal voltages before connecting the USB.
Launch the software before plugging in the smart panel meter.
