The Arbiter Systems®, Inc. Model 1040C Panel Meter Calibrator (PMC) integrates eight calibration functions: voltage, current, frequency, power, power factor, phase, reactive power (VARs), and synchroscope into one compact, portable package. All of these functions in one lightweight yet rugged instrument allow you to easily calibrate virtually every type of panel meter and many types of transducers, circuit breakers and overcurrent relays. A hand-held control is also provided, so you can operate the Model 1040C at a distance when calibrating panel meters in the control room or substation.

The Model 1040C's precision ac/dc voltage and current sources may operate independently to calibrate voltmeters, ammeters and frequency meters, or together to calibrate watt meters, watthour meters, power factor meters, VAR meters, and phasemeters.

The Model 1040C also is an excellent source for calibrating high-accuracy transducers and revenue meters, when used with an external standard. The Model 931A Power System Analyzer is a good companion instrument for these tests, with basic accuracy of 0.05% and 0.05°, built-in transducer output measurement capability and timer. The Model 931A also performs a wide variety of other measurements. Together, these two instruments can calibrate and measure the vast majority of your work load requirements.

The lower-priced Model 1040CU offers all of the same performance and features as the 1040C, but it has binding post outputs instead of detachable output cables, and it has no hand-held control unit. There is also no storage compartment in the unit's lid, and the maintenance manual is optional. For applications which do not require these features, the Model 1040CU offers significant savings.

Extensive self-test, diagnostic and calibration features are standard on the Model 1040C. Upon power-up, the self-tests verify instrument performance; should a fault be detected, it can be localized with the diagnostic functions. Calibration is performed either manually through the front panel, or automatically via the standard IEEE-488 interface.

Built-in store-recall memory for voltage, current, power, frequency, and phase settings reduces test time in complex measurement sequences. With all these features and more, the Model 1040C is a real time saver. Put one to work for you today!

Operation
Setup and operation of the Model 1040C for meter calibration is easy. The PMC output cables are connected to the device under test, and the output values for current, voltage, frequency, power or phase are set either from the front panel or remotely via the IEEE-488 (GPIB) Interface Bus.

Parameters selected from the front panel keyboard, or via GPIB, are displayed on a bright, easy-to-read vacuum fluorescent display. A settling indicator is provided to eliminate erroneous measurements. Memory, for up to 99 output settings, provids for storing frequently-used values, such as a set of cardinal points for one or more meters. Settings can also be displayed as error in percent of full scale for the meter under test. The hand-held control for remote calibration of panel meters allows operation up to 3 meters (10 feet) from the Model 1040C PMC. The standard output cables are also 3 meters long; 6-meter output cables, and a 3-meter hand-held unit extension are optionally available.

Calibration and Diagnostics
The Model 1040C's calibration and alignment feature allows adjustment of internal calibration constants from either the front-panel keyboard, or remotely via GPIB. Each operating range is calibrated for optimum performance in that range.

Extensive self-test and diagnostic features are also provided in the Model 1040C. A self-test is performed upon power-up, exercising major modules of the PMC and verifying accuracy before beginning routine operation. Diagnostic tests allow the operator to localize failures of individual circuit cards or components.

If repair should ever become necessary, the Model 1040C's design allows easy replacement of defective assemblies in minutes with simple tools.
