1. Set the 5 engineering units by button keys and the related LCD indicator will be on.
2. For zero center models, add “Z” at the end of the model. Only ranges 1~5 have this selection.
For example, DP171**Z, means the range is -30-0-30Pa.

Connection
Different models have different electrical terminals. Please wire specific model according to the wiring diagram.
DIP switch
Jumper “1” and “2”: response time settings, 0.5(default)/1/5/10 s.
Jumper “3”: LCD backlight setting, ON means backlight on, OFF means backlight off (default).
Jumper bit “4” and “5”: engineering unit setting, Pa(default)/mbar/mm wc/in wc
It should be power OFF during installing and wiring. When using 24VAC, it is strongly recommended to power the unit with
independent transformer. If sharing a 24VAC transformer with other equipments such as controllers, transmitters or actuators,
please make sure the terminals 24V and GND are connected correctly. Otherwise, it will perhaps reduce serious damages.
Before power on, make sure to complete all input / output / communication connections, dial switches and jumpers. There is a
self-inspection process of around 30 seconds after powering on, before it goes into normal working status.

● It is limited to use in indoor environment, flush mount.
● Hole size for flushing in: refer to the corresponding size in above diagram: 118x86mm ,the flush in depth is 40mm.
● Installation mode: it could be installed with preparing glue around the back of the front panel. After flushing into the hole, press
the front panel to make sure it has already tightly adhered to the wall. It could also be installed with 4 corner screws. But it is
still suggested to be properly glued before flushing in to make sure the seal with the wall.
● Connect “+” high or “-”low pressure air nozzles on the back diff. pressure box according to the actual application. The shorter
tube is better.
● When the front sample screw is not applied, the installation site may not be the real sampling point.
●When using the front sample screw, the installation site is one of the sampling points. So it should be installed on the
appropriate detecting location, with the electrical wiring upward. The specific site should be far away from frequent human
activity and source of cold, heat, humidity and air-condition outlet, with good ventilation condition.
Zero reset & Calibration
According to different environment and sensor’s characteristics, for long term of using, the sensor’s accuracy maybe drift. The
transmitter should be zero reset after initial power on to meet the specified accuracy. It is recommended to be “zero reset” after
the initial 7 days continuous working. In addition, it should be zero reset periodically in every 6-12 months’ using or confirm the
product deviation value is beyond the accuracy allowed.
Zero reset: keep the high (+)/ low (-) pressure ports unconnected in stable air, or directly connect them, press the zero button for
5s to perform “zero reset”. It means “remove the zero drift of the transmitter in order to improve the accuracy”. It is
recommended that this operation could be done periodically.
Initial zero reset: when initial power on, it should be zero reset after fully warm-up and stable (> 30min)
Long term zero drift & reset: It may have long term zero drift after continuous working; customers can reset it periodically.
Re-calibration & zero reset: when re-calibration needed, zero reset should be done first. A qualified standard manometer is
needed for re-calibration operation.
Attention
It should be power OFF during installing and wiring. When using 24VAC, it is strongly recommended to power the unit with
independent transformer. If sharing a 24VAC transformer with other equipments such as controllers, transmitters or actuators,
please make sure the terminals 24V and GND are connected correctly. Otherwise, it may reduce serious damages.
Warranty
● It has limited warranty for eighteen (18) months after the production date.
● It does not extend to any unit that has been subjected to misuse or accident.
● It is, in any event, strictly limited to the replacement or repair of the product itself.
