■ This is an example of pneumatic circuit with four sensors: three of them are connected in
parallel to the pumps and one straight to external. Two of them are protected by
overpressure valves, the other one is not protected because it has its full-scale equal to the
maximum pressure generated by pump. See following:

Electrical
The Pascal 100 or Pascal 100/IS is a multifunction calibrator.
The electrical modules can be maximum four, two of them are input modules (IN A
– IN B), and the
other two are output modules (OUT A – OUT B).
6.3.1 Electrical measurements
The instrument is able to measure voltage, current, resistance and frequency. To optimise the
resolution and get better measurement results, there are three ranges for voltage measurement,
two for resistance measurements, one range for current and three ranges for frequency.
Ranges of measurement and resolutions are specified in following table:
Range Max resolution
Voltage
(-100 …100) mV 0,0001 mV
(-2 …2) V 0,000001 V
(- 80…80) V 0,00001 V
Current
(-10 0…100) mA 0,0001 mA
Resistance
(0…400) Ω 0,001 Ω
(0…10000) Ω 0,01 Ω
Frequency
(0,4…50000) Hz 0,001 Hz
Pulse
