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 wattmeters, watt-hour 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 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.
Built-in store-recall memory for voltage, current, power, frequency, and phase settings reduces test time in complex measurement sequences.
