DPSA Series
Pressure Sensor
① Pressure unit subdisplay : The current set pressure unit is displayed.
Settings other than Mpa and Kpa are possible but not displayed.
② 2 color main dispaly : Detecting pressure value, Various display setting value
and erro contents.
③ Setting value indicator : Set pressure value, Various display setting mode.
④ Out 1 lamp : Lights during OUT1 operation.
⑤ Out 2 lamp : Lights during OUT2 operation.
⑥ UP key : Used to change the setting value in the measurement mode to higher
lever or to change the pressure unit, output mode, output mode setting,
response time, LCD color setting etc.
⑦ SET key : Enter parameter setting and save setting value.
⑧ DOWN key : Used to change the setting value in the measurement mode to
lower lever or to change pressure unit, output mode, output mode setting,
response time, LCD color setting etc.
(DPSA Series)
※
There is no short-circuit protection in analog voltage output. Do not connect this output to power supply or capacitive load directly.
※
Please observe input impedance of connected equipment when use analog voltage output.
And be sure to check voltage drop caused by resistance of extended wire.
Zero point adjustment(DPSA Series)
1. In operation mode, press the <up>key and <down>key simultaneously for more than 1 second after opening the pressure port.
2. When zero setting is completed, 0 is displayed.
* If zero setting is going on while external pressure is applied, Er1 flashes while pressing the key.
* Please perform zero adjustment periodically.

Please read the following safety considerations before use.
Safety Consideraions
※
Please observe all safety considerations for safe and proper product operation to avoid hazards.
※
Safety considerations are categorized as follows.
Warning
Failure to follow these Instructions may result in serious injury or death.
Caution
Failure to follow these Instructions may result in personal injury or product damage.
※
The symbols used on the product and instruction manual represent the following.
symbol represents caution due to special circumstances in which hazads may occur.
Warning
1. Fail-safe device must be installed when using the unit with machinery that may cause
serious injury or substantial
economic loss. (e.q. nuclear power control, medical equipment,
ships, vehicles, railways, aircraft, combustion appartus,
safety equipment, crime/disaster
prevention devices, etc.)
2. Do not use it in ammable gas because it dose not have an explosion proof construction.
Failure to follow this instruction may result in explosion.
