equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this meter to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the meter.

The 1950 Series provides the user the ultimate in flexibility, from its
complete user programming to the optional setpoint control and communication-
capability. The 1950 accepts a DC voltage or current input signal and provides a
display in the desired unit of measure. The meter also features minimum and
maximum display capture, display offset, units indicator, and programmable-
user input. The display can be toggled either manually or automatically between
the selected displays.
The 1950 display has 0.48" (12.2 mm) high digits. The LCD is available in two
versions, reflective or red/green backlight. The backlight version is user
selectable for the desired color and also has variable display intensity.
The capability of the 1 9 5 0 can be easily expanded with the addition of
option modules. The setpoint output cards are field installable with
programmable setpoints. Serial communications capability for RS232 or RS485
can be added with a serial option module.
The 1 9 5 0 can be powered from an optional N O S H O K Micro-
Line/SensorPower Supply (PS3), which attaches directly to the back of a 1950.
The PS3 is powered from 85 to 250 VAC and provides up to 400 mA to drive the
unit and sensors.
The 1950 is a DC Process meter. It features voltage and current input ranges,
that are selected by the user via a programming jumper and software input range
selection. The ranges consist of the following: 0 to 10 V, 0(4) to 20mA, or 0 to
50 mA. Users should select the appropriate voltage range that covers their
maximum input.
