Single Phase Reference Standard Meter

Single Phase Reference Standard Meter

The Single Phase Portable Reference Standard (SPRS-1102) from SANDS is a portable meter test equipment that helps to calibrate the error present in the single-phase energy meter i.e. the meter under test (MUT). The SPRS supports both static and electro-mechanical types of meters. It can also be used to compute the voltage, current, energy, phase angle etc of the meter under test. It has an LCD display and an alphanumeric keypad to suit the user. It can be interfaced with the PC for analysis. It has the capability of storing 1000 test results.
