Meter box assembly

A meter box assembly capable of displaying the remote voltage from an external voltage source or the voltage output from an external strain gage transducer, said meter box assembly comprising a housing, said housing having at least one display unit therein, said display unit being in the form of means for displaying said remote voltage or said voltage output from said strain gage transducer, a switching means electrically connected to said display means, a voltmeter circuit, said voltmeter circuit being electrically connected between said external voltage source and said switching means, a strain gage circuit, said strain gage circuit being independent of said voltmeter circuit and electrically connected between said external strain gage transducer and said switching means, said strain gage circuit having a strain gage conditioning module, a switch module, a calibration resistor and an indicator lamp circuit, said external strain gage transducer being electrically connected between said conditioning module, said calibration resistor, said switch module and said indicator lamp circuit, whereby in accordance with the position of said switching means, said display means registers either said remote voltage from said external voltage source or said voltage output from said external strain gage transducer.
