Test set T-113; manufactured by Autophon AG, Solothurn.

In addition to the T-112, the T-113 test set was developed by Autophon for alignment and repair work on the SE-125 handheldf radio and was used in field repair workshops.

• Principle: Stabilised power supply, various set-specific measuring functions.

• Mains operation: 220 V

• Universal instrument (multimeter) Elmes 20A for DC and AF signal measurements. The RF probe must be used for RF measurements for signal tracing.

The T-112 test set developed by Autophon was designed for maintenance and alignment work on Autophon SE-125 handheld radios in the 1st or 2nd repair stage. The T-113 was developed for more complex repair tasks.

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 be measured in the same way as with the T-112. When working on the SE-125, its own battery must be removed.

The supply voltage is stabilised; in the event of an overload due to a short circuit, the red lamp lights up and an electronic fuse switches off the power supply.

Various device-specific measurements can be carried out with the 29-position measuring switch; I do not have the corresponding operating documents.

Set-specific measurements.

The set is completely solid state.

The T-113 was developed for tuning and alignment work on the SE-125 radio from Autophon.

The P-667 test set developed for the SE-125 by the company Electime includes the functions of the T-112 and T-113 test sets and was also used in the repair workshops.
