The load resistance of pulse output should be used to 1kΩ, 2W.If no translation of the pulse output possible by the cable length or the frequency of the pluse output,the load resistance should be selected by calculation as shown below.

Example of CEV cable capacitance 0.1µF/km

WhereE = Supply voltage (V) f = Frequency of pulse output (kHz)R = Value of load resistance (kΩ)

C = Cable capacitance (µF) P = Power ratio of the load resistance (mW)

6.2.2 Adjusting Zero Point for Gauge/Absolute Pressure Transmitters

(1) When you can obtain the Low Range Value from the actual measured value of 0% (0 kPa, atmospheric pressure);

For pressure measurement using gauge pressure transmitters,followthestepsbelowbeforeperformingzeropointadjustment.
