P-667 Test set; manufactured by Electime AG, Biel.

Electime Biel developed the P-667 test set, designed for use in repair workshops, for alignment and repair work on the widely used SE-125 field radio. It allows similar checks on the SE-125 like the T-112 and T-113 test sets, but external sets such as a signal generator, a frequency counter and a deviation meter must be connected.

• Principle: Stabilised power supply, wattmeter and voltmeter.

• Mains operation: 220 V

• External signal generator and frequency counter as well as a FM deviation meter

The P-667 test set developed by Electime allows maintenance and alignment works on the Autophon SE-125 handheld radios.

The SE-125 radio to be tested can be supplied with power directly from the test set; in addition to the nominal voltage of 7.5 V, overvoltage and undervoltage can also be checked. When working on the SE-125, its own battery must be removed.

The set is completely solid state.

The P-667 was developed for test and aligment work on the SE-125 field radio from Autophon in the maintenance workshops.
