– Plug-in power supply 5 V – Windows Software VACTEST Explorer Product Description The VACTEST PPP 700 D is measuring total gas pressure in the range 1.0 x 10 - 1200 mbar, addition- ally relative pressure in a maximum range of -1060 ... +340 mbar.
VACTEST PPP 700 D Improper Use The use for purposes not mentioned above is regarded as improper, in particular: – Connection to pumps or units which are not suitable for this purpose according to their operating instructions. – Connection to components containing touchable, voltage carrying parts.
Installation Installation NOTE The device shall be installed by trained personnel only. Unauthorized modifications of the in- strument are not allowed! Notes for Installation Installation location: Indoor Temperature: +5 °C ... +60 °C Rel. humidity: max. 80% up to 30 °C, max. 50% at 40 °C, non-condensing Vacuum Connection CAUTION Unintended opening of clamp with an overpressure in the vacuum system over 1000 mbar.
PC or a suitable charging adapter. Bluetooth® Interface The VACTEST PPP 700 D is equipped with a Bluetooth® Low Energy interface. It can be used for wire- less upload of measurements or stored measurement data.
General Measurement Principle The VACTEST PPP 700 D is equipped with an internal combination of a piezo-resistive diaphragm sensor and a Pirani sensor, which uses the heat conduction of the gas for measuring vacuum. An- other piezo-resistive sensor measures ambient pressure.
Operation Handling Press the OK-Key to switch on the device. After approx. 2 seconds the display will show the measure- ment menu with the actual pressure. To switch off the device press and hold the OK-Key for 3 seconds. Measurement: Change operation mode / Keylock Menu: Move upwards / Increment input value Measurement: Change additional info / Reset Min/Max Menu: Move downwards / Decrement input value...

Operation Operating Mode In the measurement menu operating modes “Continuous“ (continuous operation) or “Auto-Off“ (au- tomatic switch-off) can be selected by means of the “Arrow Up“ key. In continuous operation the device remains powered on without limit or until an editable maximum operation time has elapsed, depending of the device configuration.
Operation Start and Stop Data Logging Your VACTEST PPP 700 D can be operated as data logger. Multiple measurements in separate data files of type VACTEST Explorer (*.vgw) can be saved in the internal memory. Memory size will be suf- ficient for several million data points.
Operation Graph The VACTEST PPP 700 D can plot measurements as pressure-vs-time diagram. Diagram options can be adjusted as described in section 4.6.2 Diagram-Options. [➔ 17] To start plotting measurements in a diagram select item “Graph“ from the main menu: Depending on the diagram settings pressure readings will now be plotted over time.
Operation Calculation of Leakage Rates By means of a rate-of-rise measurent the VACTEST PPP 700 D is able to calculate the leakage rate of a vacuum system. To start a rate-of-rise measurement select “Leakage Rate“ from the main menu: In the next step the internal volume of the vacuum vessel or system has to be entered. After confir- mation of the adjusted value by means of the “OK“...
Operation 4.6.1 Logging Mode Select item “Logging Mode“ in the “Settings“ menu to adjust parameters for data logger operation, i.e. logging interval and an automatic stop after a desired time limit. Logging Interval Measurement data will be stored with this adjustable time interval after the data logging is started. The edited value must finally be confirmed with the “OK“-key.
Page 16
Operation CAUTION Logging interval and required logging period should match to avoid unnecessarily high data volumes! This function will terminate data logging automatically after an adjustable time limit. In the first step the function has to be enabled or disabled. To enable select “On“ and then “Arrow right“...
Operation 4.6.2 Diagram-Options By selecting item “Graph“ in the “Settings“ menu you can adjust parameters for the graphic display of measurements as a pressure-over-time diagram, i.e. data source, time mode and axis options. Graph Mode Under this menu item you can choose whether the pressure-over-time diagram will show all mea- surements beginning from the start of the plot (“Zoom“) or whether measurements are plotted in a rolling mode within an adjustable time frame including the current reading (“Roll“).
Page 18
Operation Graph Window If a rolling mode has been selected as “Graph Mode“ this menu item will allow to set the required time frame for the diagram. The setting must finally be confirmed with the “OK“-key. Graph Axis Use this menu item to select whether the y-axis of your plot shall have linear or logarithmic scaling. The setting must finally be confirmed with the “OK“-key.

Operation 4.6.3 Sensor Choose menu item “Settings“ / “Sensor“ to re-adjust the sensors of your VACTEST PPP 700 D. Further you can set parameters for gas type correction and, with combination sensors, the transition mode between the sensors. Adjust This function is used to re-adjust the sensors. Select between “Adjust Zero“...

Page 22
Operation Gas Correction Factor The pressure reading of Pirani sensors depends on type and composition of them gas being mea- sured. The unit is adjusted for N and dry air. For other gases the pressure display can be corrected in the range below 0.5 mbar by multiplication with a related correction factor. You can select pre-defined factors for common process gases or set a user-defined value.

Operation 4.6.4 Device Settings Under menu “Settings“ / “Device“ you can change basic settings of your VACTEST PPP 700 D. Alarm Buzzer With this function an optic and acoustic alert function can be activated. Under “Datasource“ you can initially activate the alarm buzzer and select which measurement signal should trigger the alert.
Page 26
Operation Under “Volume“ the loudness of the alert signal can be adjusted. Depending on the settings made under menu item “Switch Mode“ the alert will be triggered, as soon as an adjustable threshold is under- or overshot or if a device error has occurred: The thresholds to switch-on and switch-off the alert can be edited under menu “Switch Values“.
