1.3. Electrical connections
**** The electrical power supply of the GP500 must be equipped with a protection system against the leakage currents adapted to the device’s power.

**** Any intervention or electrical connection must be carried out by a formed and qualified technician. The device must be turned off.
Before connecting, check the type of power supply indicated on the product.

Use of the GP 500

2.1. Turn on the device
To turn on the GP500 :
➢ Connect the GP500.
It is not compulsory to connect the GP500. Its internal battery has 8 hours of autonomy. However, in case of extended use, it is recommended to connect it on the main power source.
➢ Press on “On/OFF” at the top right of the user interface.

2.2. Configure the device before measurement or a generation
2.2.1 Activate or deactivate the automatic autozero
➢ Press on “Param.”.
➢ Go to the line “AutoZ” and press on OK.
➢ With the arrows select “ON” to activate the automatic autozero or “OFF” to deactivate the automatic autozero.
This autozero will perform every 20 seconds for a measurement lower than 100 Pa, every minute for a measurement lower than 1000 Pa, and every 5 minutes for a measurement higher than 1000 Pa.
➢ Press on OK to validate.
➢ Press on ESC to return to the measurement display.

2.2.2 Set the integration
The GP500 pressure measurement element is very sensitive and very reactive to pressure changes. During measurements on an unstable aeraulic network, the pressure measurement becomes illegible. The integration coefficient (from 0 to 9) then allows to smooth the pressure measurement in order to avoid untimely variations and allow the exploitation of a more stable measurement.

➢ Press on “Param.”.
➢ Go to the line “Integration” then press on OK.
➢ With the arrows select the desired integration between 0 and 9.
➢ Press on OK to validate.
➢ Press on ESC to return to the measurement display.

2.2.3 Select the unit
➢ Press on “Unit” .
The unit currently used displays at the top of the screen.
➢ With the arrows select the desired unit: Pa, daPa, hPa, mmH2O, mmHg, bar, and inWg.
➢ Press on OK to validate.
2.2.4 Perform a manual autozero
➢ Press on to trigger the autozero.

2.3. Set the customer’s corrections
The customer’s corrections allow checking that the GP500 measures and generates correct values. The values measured and generated by the GP500 are compared with a standard, and then can be corrected on the GP500. Two types of generations can be performed :

• Internal generation: the device generates pressure on the standard. The number of generated points and their setpoints are not modifiable.
• External generation: the device generates pressure on the standard. The number of generated points and their setpoints are defined by the user.

➢ Press on “Param.”.
➢ Go to the line “Customer corrections” then press on OK.
➢ A-frame displays on the screen, with the keys enter the code 0101 then press on OK.
The menu “Customer corrections” displays on the screen.

2.3.1 Visualize the points
➢ Go to the line “Show items” then press on OK.

➢ Generate a setpoint with the calibration pressure bench.
The GP500 displays the measured value.
➢ Compare this value with the value measured by the standard device.
➢ Press on OK.
➢ Enter the value measured by the standard device then press on OK.
The GP500 goes to the second point.
➢ Generate a second setpoint with the calibration pressure bench.
The GP500 displays the measured value.
➢ Compare this value to the value measured by the standard device.
➢ Press on OK.
➢ Enter the value measured by the standard device then press on OK.
➢ Follow the same procedure for the next points.

**** The first point to compare must be the minimum value of the GP500 measuring range(-2499 Pa or -9999 Pa depending on the GP500 type) and the last point to compare must be the maximum value of the GP500 measuring range (+2499 or +9999 Pa depending on the GP500 type).

When this pressure is stabilized, the green led flashing stops.

Perform a leak test

The GP 500 allows to test an existing aeraulic network and thus verify if leaks are present in this network.
➢ Press on “Test”.
The “Leak test” screen displays. This screen allows configuring the test and then starting it.
➢ Go to the line “Order” to set the setpoint that the GP500 must reach then press on OK.
➢ Enter a setpoint between -10 000 and +10 000 Pa or between -2500 and +2500 Pa depending on the GP500 type.

➢ Go to the line “Duration” then press on OK to adjust the duration during which the generator performs the test.
➢ Adjust the duration with the numeric keypad then press on OK.

Once the adjustments are performed, the GP500 must be connected to the network to test.
➢ Perform the connection between the network and the “Generation” pressure plugs of the device thanks to the provided silicone tubes and connectors DN2.7.

The test can now begin :
➢ Go to the line “Start test” then press on OK.
The GP500 generates the setpoint pressure and then maintains it during the test duration.
