User Switch
The user switch can be used to perform vacuum zero or atmospheric
adjustment. Refer to Operating Manual 300544657_002 before pressing the
user switch.
Calibration and adjustment
The transmitter is factory calibrated when delivered. Additional adjustment is
normally not required. Refer to Operating Manual 300544657_002 for
calibration and adjustment recommendations.
Installation
Install the PTR 90 N away from pumps and gas sources and where vibration is
minimized to give the most representative pressure measurement. The PTR 90
N can be mounted in any orientation, without compromising accuracy and
performance. Refer to Operating Manual 300544657_002 for installation
specifications and recommendations.
Electrical Connection
Use a cable with a male RJ45/FCC68 or male 15 pin HD Sub D connector with
strain relief to ensure proper electrical connection and to reduce stress on the
connectors.
To comply with EN61326-1 immunity requirements, use a braided, shielded
cable. Connect the braid to the metal hoods at both ends of the cable with the
end for power supply connected to earth ground.
The PTR 90 N is not intended for use in corrosive or explosive
environments. Refer to materials exposed to vacuum for
process compatibility.
Ensure a low impedance electrical connection between the
PTR 90 N transmitter body and the grounded vacuum system
to shield the sensor from external electromagnetic sources.

Analog output
The analog voltage output (16 bit resolution) provides a logarithmic 0.6
VDC/decade. Connect the signal to a differential input.
Analog output voltage vs. pressure graph (Nitrogen)
Gas dependence
The PTR 90 N transmitter is based on measurement of thermal conductivity (for
the MP-sensor) and consequently its reading depends on gas type and gas
concentration. The transmitter is calibrated for Nitrogen, and will read higher
pressure values when exposed to atmospheric air. For more information, refer
to Operating Manual 300544657_002.
Do not connect the negative side of the analog output to the
power supply return or to any other ground. The voltage drop
from supply current will produce errors in the analog output.
