OMEGA OMNI-CAL PORTABLE TEMPERATURE CALIBRATOR & SIMULATOR

Description: NO OVERSEAS/INTERNATIONAL BIDS!!!! Sale is intended for the U.S.A only. NOTE: Please contact me for a shipping rate quote if you live in Alaska or Hawaii. I retired a while ago after spending the majority of my career working in testing and calibration labs and relocated to the northeast. I wrote calibration procedures and was the calibration procedure release focal for the largest aerospace manufacture in the U.S.A. My main area of interest was in physical/ dimensional metrology. I also participated in writing many ASME B89 dimensional metrology standards. I purchased this item a number of years ago with the intent of opening my own calibration laboratory someday. I performed a “functional test” only of the Omni-Cal-4A as follows:1.) As a calibrator providing precise mV voltage outputs fed to a HP 3457A multimeter (see photos)NOTE: The “E” displayed to the far right in the display, is an annunciator for emf (millivolts), according to the Operator’s Manual (pages 1-1 and 6-2).2.) As a thermometer providing direct °F or °C readout of a connected K type thermocouple. Readings were taken at ambient temperature.NOTE: The Hewlett-Packard 3457A multimeter shown in the photographs is not included with this sale and does not have a current calibration/certification.NOTE: I do not have the necessary standards (as listed in the operator’s manual) to perform a NIST tracable calibration of the Omni-Cal. Due to its age, and the nature of vintage test equipment it is being sold “AS-IS”. All SALES ARE FINAL. NO RETURNS.This listing is for the following:(1) Omega OMNI-CAL-4A-110 and (1) Omega OMNICAL 4A and OMNI CAL 8A Temperature Calibrators Operator’s Manual (photocopy). NOTE: The NiCad battery pack has been charged for 15 hours (per the operator's manual). However, it may need replacing at some time in the future. The features noted below are taken from the Omega Operator’s Manuals and sales literature and may not reflect the actual performance and options of the item for sale and is provided as an overview and for informational purposes only. I will not be held responsible for its accuracy and/or content.The OMNI-CAL™ is a microprocessor-based, laboratory grade, field portable, digital calibrator, thermometer, and voltmeter. It is packaged in a rugged metal case, and it is especially designed for multifunction use in the harsh environments of the process and service industries. The OMNI-CAL™ operates in any of four front panel selected functions:1. As a thermometer (FUNCTION = MEASURE), providing direct °F or °C readout of a connected thermocouple.2. As a calibrator (FUNCTION = CALIBRATE), providing precise voltage outputs equivalent to the tabular values expected from a selected thermocouple at a settable temperature, or a settable voltage from – 12 to + 80mV.3. As a voltmeter (Function = MEASURE, RANGE = mV), providing a 4-1/2 digit readout of a ± 101 mV range input, with microvolt resolution and automatic polarity indicated in the display.4. As a self-tester (FUNCTION = TEST), providing an overall system performance check, assuring a valid calibration. Appropriate microprocessor generated error messages are displayed for malfunctions that may occur during other functional use. The OMNI-CAL-4A is a 4-range model supplied for 110V ac recharging power sources. This model is configured for the mV RANGE selection, thus providing the millivoltmeter and direct settable voltage functions. This 4-range model provides for three thermocouple ranges (J,K,T), in addition to the mV range.Measurements and calibration outputs for front panel selected thermocouple types are automatically corrected for reference junction offsets. Direct millivoltmeter measurements and settable direct reading calibration voltage outputs are provided without reference junction compensation.Front panel displays are presented on large 0.31” (8 mm) high, LEDs. The decimal point is positioned automatically, and the minus (-) polarity sign is displayed for any negative value; the plus (+) polarity sign is understood for any positive value. The digital display is actually 7 positions; five decade positions are available for the 4-1/2 digit value; the decimal point is incorporated to the right within one of the positions; the polarity sign (when appropriate) is always positioned to the far left; the symbol F, C, E is displayed to the far right, as annunciators for Fahrenheit, Celcius, or emf (millivolts), respectively.Error messages of HIGH, LO, OPEN, or ERROR are respectively displayed when the temperature is above full scale, the temperature is below full-scale, an open thermocouple is detected (or less than 101 mV), or when a voltage greater than 101 mV is applied to the input terminals. The “Omni-Cal-4A-110” will only be shipped by UPS ground (signature required) within the U.S.A. I will not ship to post office boxes, unconfirmed addresses or third parties.
