WARNING! Electric shock danger
ProSense QPS is a pressure measurement device. DO NOT use it out of its specification. Improper
pressure or incorrect wiring may cause injuries to staff or damages to other devices.
1. Keep away from high-voltage and high-frequency environment during the installation to prevent
interference. Avoid using the device in environments which contain: (a) dust or corrosive gas; (b)
high humidity and high radiation; (c) shock and vibration
2. QPS can only be used for air pressure measurement and should avoid corrosive, inflammable or
toxic gas measurement.
3. Make sure the input power is switched off when installing or uninstalling the QPS and the pres-
sure source is off to prevent harm to personnel or equipment.
4. Before switching on the input power, check the signal connection, e.g. the input voltage and
polarity. Voltage that is too high may cause damage to the QPS.
5. Use dry cloth and DO NOT use acid or alkaline liquid to clean the device.
6. Outputs remain active in Setup Mode.
