Voltage supply DC 24 V (50 mA) (can be activated via menu)
1
Measuring input, voltage (max. DC 0 ...12 V)
2
Measuring input for current or switch test (max. 24 mA)
3
Power connection/Charging socket or connection of the power supply unit
4
Connection to the USB/RS-232 interface
5
1) Connections: 4-mm test sockets
WARNING!
Physical injuries, damage to property and the environment due to electric shock!
Improper handling can lead to dangerous situations and injuries, since voltages may be applied on the
components.
▶
Only connect original WIKA components to any of the electrical connection sockets.
▶
Only use the supplied charger!
▶
Only use the supplied test cables!
▶ Only use the supplied interface cable!
▶
Only make or disconnect any electrical connections while the pressure calibrator is switched off.
▶
Make sure that the operating voltage specified on the charger corresponds to the local mains voltage.
▶
Do not overload the measuring inputs (see 10 "Specifications").
▶
If the test item has its own power supply, switch off the internal DC 24 V voltage supply via the menu.
▶
Take care to connect to the correct terminal +/- of the electrical connections!
If the pressure calibrator is set for reading from test items with voltage outputs (e.g. DC 0 ... 1 V / DC 0 ... 2 V / DC 0 ... 5 V /
DC 0 ... 10 V) and no test item is connected to the measuring input (voltage), then a non-zero value will be shown for the test
item on the display.
This is not an error, it is simply due to the electrical design of the measuring input.
▶
The internal DC 24 V voltage supply must not be short-circuited nor should the max. output current through the snubber
circuit exceed 50 mA.
▶ In addition, it should not drop below 20 mA, in order to ensure an accurate current measurement.
