Operation is similarly easy as for the 6112B. The large rotary switch provides five positions Off / Battery Condition / three measuring ranges. This means that the range has to be selected manually. The small switch for the time constant is no longer required in standard operation because the microprocessor automatically selects the time constant. The instrument does not provide a speaker and thus has no alarm thresholds. An earphone can be connected at the instrument's side. The original model 6112D-100 (without the /H suffix) is designed for the old quantity Hx. In 2001 we created the model 6112D-100/H for the quantity H*(10). We did not aim at a PTB approval because of the relatively low demand for this Teletector model in Germany.
