4.2 Display
After switching on, the unit performs a pressure zeroing for a few seconds.
ATTENTION!
During zeroing, no hose may be connected and no differential pressure applied, as the unit stabilizes and determines its zero point.
The measurement display then appears.

Settings

• Immediately after switching on, as soon as the battery symbol appears in the display and be- fore the measured value display appears, double-click with the operating button.

This takes you to the settings mode.
5.1 Selecting the pressure unit
Press unit appears in the display.

• To select the pressure unit, press the operating key briefly.

The pressure units mbar, bar, inWC, psi, mmH2O, mH2O, in HG, Pa, hPa, kPa and MPa appear in succession.

• Accept the desired unit with a double click.

5.2 Selecting the pressure resolution
The display shows “reso” (resolution).
You can now set the displayed resolution for printing. The resolution refers to the previously selected print unit. There are 3 different resolutions to choose from.

• Press the operating key briefly to select the desired resolution.
• Confirm your selection with a double click.

5.3 Selecting the temperature unit
Temp. unit” appears in the display.
You can now select the temperature unit °C or °F.

• Press the operating button briefly to switch between °C and °F.
• Confirm your selection with a double click.

Error Message

If the error message BLE appears in the display, the device does not recognize the Bluetooth module. In this case, the Wöhler SC device must be sent in for service.

Water connection components

• For better accessibility or readability, you can also use the 90° angle adapter (art. no. 8841).
• To connect to a tap, first screw the angle adapter (art. no. 8841) onto the pressure connection of the unit (see fig. 3, part 5).
• Screw a measuring adapter suitable for the tap (Art. No. 8856 or 8857) onto the angle adapter.
• oder 8857) auf den Winkeladapter.

ACHTUNG!
Please always use the angle adapter. If the Wöhler SC 660 is mounted on the tap without the angle adapter, water may run over the unit during the disassembly.

• You also have the option of connecting the measuring device to the lead behind the wall panel. For better accessibility or readability, you can also use the 90° angle adapter (art. no. 8841).

Pressure tests on water pipes

Connect the device to the Wöhler SC 660 app as described in the app instructions. Select the menu “Water.

• Call up the menu item “Pressure test”.
• Connect a temperature measuring clamp to the Wöhler SC 660 and measure the tempera- ture of the water pipe.
• Tap on the temperature value “Media temperature” in the app and then enter the measured temperature as the media temperature in the app.
• Tap on the blue field “Ambient temperature” to accept the measured temperature value or tap on the field of the temperature value to enter it.
• Enter the desired test pressure, stabilization time and measurement time if you want to change the pre-set values.
• Tap the icon for zeroing the pressure if you want to zero the pressure sensor.
• Tap on “Start measurement”.

• Apply the desired test pressure to the water pipe.
• The stabilisation phase follows.
• After the stabilisation phase, the measurement starts automatically. During the measurement, the pressure curve can be followed in a graph.

• After the measurement has been completed, the result display appears.

• Tap on “Generate PDF” if you want to generate one of the pressure measurements.

NOTE!
If you are working with Adobe Reader, you can directly download the PDF protocol in the display.

• In the PDF, tap the Share button in the footer if you want to send or save the protocol.

Connection for measuring the line temperature

• To measure the line temperature, connect the clamp temperature sensors to the underside of the Wöhler SC 660, see Fig. 3, No. 1.

Air-conditioning and refrigeration connection

• For pressure measurement on refrigeration systems use the Wöhler connection valve Art. No. 62694.
  NOTE!
  The connection valve ensures that the refrigerant loss during the measurement is as low as possible.
• Screw the connection valve onto the measuring socket.

Air-conditioning and refrigeration connection

• Screw the Wöhler SC 660 tightly onto the ex- ternal thread of the connection valve so that the circuit is closed again.
• Screw in the blue knurled screw until the Schrader valve of the measuring nozzle is open.
• After the measurement, unscrew the blue knurled screw again so that the valve of the measuring connection closes again and no refrigerant escapes when the Wöhler connection valve is dismantled.

Power supply

The battery status is indicated at the top of the unit display by the battery symbol. If the battery voltage is low, proceed as follows
11.1 Changing the battery 

• Switch off the unit.
• Remove the battery cover on the back.
• Replace the batteries with 2 new 1.5 V AA LR6 batteries.
• Observe the correct polarity according to the labelling in the battery compartment.
