page 4 of 17 Safety information! Remove all packing materials, remove the equipment from its packing-box, remove the protective covers and inspect the equipment. If the equipment is damaged, notify the supplier and the carrier in writing within three days; state the item number of the equipment together with the order number and the suppliers´ invoice number. Retain all packing materials for inspection. Do not use the equipment if it is damaged.
page 5 of 17 Ensure that maintenance is done only by suitably trained and supervised technicians. Ensure that the maintenance technician is familiar with the safety procedures which relate to the equipment processed by the vacuum system and that the equipment if necessary is approximately decontaminated before starting maintenance. Use only genuine spare parts and accessories. ☞ Otherwise safety and performance of the equipment as well as the electromagnetic compatibility of the equipment might be reduced.

page 8 of 17 Description VAP 5 The vacuum gauge VAP 5 relies on the fact that the thermal conductivity of the residual gas in the vacuum chamber is a measure for the gas pressure. The thermal conductivity of gases is proportional to the pressure within a certain range and is related to the molecular mass. The thermal conductivity of gases and vapours varies with their molecular mass. The gauge has been adjusted for air (nitrogen) at the factory.
page 9 of 17 Interface parameters Interface parameters at the COM port have to be set as follows (the interface parameters at the DVR 5 cannot be changed): Interface parameter Baud rate 9600 Data bits 8 Star t bits 1 Stop bits 1 Parity none Handshake none Via the interface the actual pressure value can be read out. Interface command "IN_PV_1" readout of pressure value Output "XXXX.X [unit]" "-1" resolution of 0.

page 11 of 17 Instructions for repair with directions for repair and spare parts list is available on request. ☞ The instructions are for trained service people. Cleaning the gauge head The gauge itself is maintenance-free. ➨ Only VSP 5: Using small screw driver or pencil tip, release locking ring in gauge head connection and remove protective filter with shim, keep locking ring. ➨ Fill the gauge head chamber with a solvent (e. g. benzene) and allow sufficient cleaning time.
page 12 of 17 Adjustment under vacuum: ➨ Evacuate gauge head to a pressure < 5 x 10-4 mbar. Status indication vacuum is displayed. Note: Adjustment under vacuum with an actual pressure > 5 x 10-4 mbar reduces the accuracy of the measurement. ➨ Push key-button at the side of the housing with a pencil tip or a small screwdriver. Status indication readjustment is displayed. ➨ Push key-button again in order to adjust pressure reading to 1 x 10-3 mbar. Status indication readjustment vanishes.
page 13 of 17 Adjustment under vacuum: ➨ Evacuate the device to a pressure < 5 x 10-2 mbar. Note: Adjustment under vacuum with an actual pressure higher than 5 x 10-2 mbar reduces the accuracy of measurement. If the pressure is significantly higher than 5 x 10-2 mbar, adjustment to a reference pressure is recommended. ➨ Push key-button at the side of the housing by using a pencil tip or a small screwdriver. The reading is automatically adjusted to “zero“.
