Adjustment of activation
and instrument detection
MIC board 30128-200
Setting the instrument detection
• The setting takes place in program 12 MIC.
• Connect a resistor of 51 R, ± 1% and 0.2W to the test line.
ATTENTION!
The original ERBE TEM connecting cable EE 20192-086 has a cable impedance of 1 Ohm per cable, which
produces a series resistance of 2 Ohms for the instrument detection. In the line to and from the unit the
instrument test line must have a series resistance of < 0.5 Ohm. Since on the V4.00 version only the TEM
instrument no. 1 and MIEN probe no. 1 are connected up, it is sufficient to perform the balance only for
these instruments.
With jumper JP4 on the front panel the measurement display is activated.
