1.0 GENERAL INFORMATION This manual contains technical and general information concerning the installation, operation and calibration of the Hastings HVC-282 Vacuum Gauge, and associated components. For proper operation, the Hastings HVC-282 Vacuum Gauge must be suitably connected to a Hastings Model DV-273 Gauge Tube. Attempting to use this Vacuum Gauge with any other transducer may damage the gauge and or transducer. 1.
Hi / Lo Relays ............................................................................... SPDT N.O./N.C. up to 125VAC 10A or 277VAC 6A With onetime ≈10sec. delay to prevent relay chater, only during unit power up. Operational Limits ....................................................................................... 00 to 50OC <80%RH non-condensating. Storage: -200 to 500C (Non-operational). Size ........................................................................................................
2.0 GAUGE TUBE AND CABLES 2.1 Gauge Tubes: Octal sockets of standard metal tubes are color-coded for easy identification; DV-273 is dark blue. The tubes are to be installed in 1/8" NPT female thread, or in a Hastings type OS Quick Connector. Maximum overpressure of gauge tube is 150 psi. Construction of shell is of Nickel-plated steel. See section 1.2 for Operating Principle. 2.2 Gauge Tube Cables: The four color-coded wires (Black, Red, White, Green) are connected as shown on the label on the top of can.
3.0 INSTALLATION 3.1 Panel Mounting: Section 8 of this manual shows an outline drawing detailing panel cutout for a standard Hastings CVT Gauge. Install the meter on the panel using the supplied hardware. 3.2 Gauge Tube Installation: Situate the gauge tube in a clean, dry vacuum system with the open end pointing down so as to be self-draining should any vapors condense in it (see Section 6.0).
4.0 OPERATION 1) Plug in power cable into any single or two phase AC line for 115VAC or 220VAC 50/60Hz operation, per unit configuration. To change input voltage configuration, remove all connecting wires to rear terminal strips, then removing two small screws at rear, remove can. On lower PC board push slide switch toward rear of can for 115VAC, and toward front of can for 220VAC, reassemble in opposite order. Remark can as to new voltage configuration.
5.0 CALIBRATION AND TROUBLESHOOTING GUIDE All Hastings Vacuum Gauges and Gauge Tubes have been carefully checked and calibrated at the factory before shipment. If a calibration check is desired, the methods in the following sections may prove helpful. 5.1 Checking of Tube: The simplest and quickest method of checking operation and calibration of a gauge tube is to keep a new spare clean gauge tube on hand as a “standard”.
f) Adjust outside pot to read 2.630mV ±5µV on DVM. g) DV-273 gauge tube is now calibrated. HVC-282 calibration. Course adjustment (Caution: Resistor connections are not to any power terminals.) a) With power off, connect an 86.6 ohm 1% 1/8W resistor to tube terminals white & green. b) Connect a 28 ohm 1% 1/8W resistor to tube terminals red and black. c) Connect a DVM to measure mV across the 28 ohm resistor with (+) lead to red terminal.
6.0 NOTES ON VACUUM MEASUREMENT 6.1 Effects of Condensable Vapors: If the readings of Hastings Vacuum Gauges are to be compared with readings of other types of gauges, consideration must be given to the possible effects of condensable vapors in the system on the other gauges. For example, none of the many types of the McLeod Gauge give correct readings if condensable vapors such as water, alcohol, acetone, etc., are present in the system/gauge.
7.0 SERVICE INFORMATION 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.
