3.0 Installation 3.1. Receiving Inspection Unpack unit and inspect all items for obvious signs of damage. Immediately advise Teledyne Hastings and the carrier of any suspected damage. In the unlikely event that items need to be returned, first obtain an RMA (Return Material Authorization) number from our Customer Service Department at 1-800-950-2468. 3.2. Vacuum Sensor (DV-4 or DV-6 series) Figure 3-1 shows a typical Hastings thermocouple vacuum tube.
4.0 General Information Operation of the Hastings gauge sensor (DV-4 or DV-6) is based on a low voltage AC bridge that heats a noble metal thermopile. A change in pressure in the gauge tube alters the molecular collision rate and therefore the thermal conduction of the gas or gas mixture surrounding the thermopile. This causes a temperature shift in the AC heated thermocouples A and B (Fig. 3-1).
c. Pressure under range “-0.00 to -0.05” (negative display values) indicating that the instrument requires low-pressure adjustment. Refer to Section 4. 3. Always place slide switch to the off position when not in use. This will help prolong the life of the battery.
5.0 Calibration 5.1. Calibration in a Vacuum System 1 Install a DV-4 or DV-6 sensor in your vacuum system and evacuate vacuum chamber to a pressure less than 1.00E-04 Torr. NOTE: Refer to Fig 3 for locations of calibration pots. Adjust only the pot that corresponds to the particular type of sensor tube installed (DV4 or DV6). 2 DV-4 or DV6 zero adjustment pot: a. Remove battery compartment cover. b.
1 DV-4 low pressure adjustments: a. Connect instrument gauge cable to a DB-16D Reference Tube and position slide switch to DV-4. b. Remove battery compartment cover, and then adjust DV-4 calibration pot until display reads pressure value listed on reference tube label. c. Set slide switch to OFF position and disconnect gauge cable from sensor. d. Reinstall battery compartment cover. 2 DV-6 low pressure adjustment: a.
6.0 Maintenance 6.1. Authorized Maintenance The HPM 4/6 Power Supply/Display does not require maintenance other than routine battery replacement and calibration. Note: A low battery will be indicated by “LOBAT” appearing in lower left corner of LCD display. In the unlikely event that the HPM4/6 fails or is damaged, only qualified Teledyne Hastings personnel should attempt repair.
7.0 Warranty 7.1. Warranty Repair Policy Hastings Instruments warrants this product for a period of one year from the date of shipment to be free from defects in material and workmanship. This warranty does not apply to defects or failures resulting from unauthorized modification, misuse or mishandling of the product. This warranty does not apply to batteries or other expendable parts, nor to damage caused by leaking batteries or any similar occurrence.
