1 Operating Elements and Connections
1 Range switch
2 Button “0Ω CAL. SW” for bridging the jacks “ COM” (4) and
“V.Ω.A” (10) for the 0 Ω calibration (with model MT-300 only):
while 0 Ω calibrating, keep this button pressed, by this the
short-circuiting of the test lead tips is not necessary which is
otherwise usual
3 Plug-in connections for testing transistors, with LEDs situated
above to indicate the transistor type (with model MT-300 only)
4 Jack “ COM” for the black test lead (negative pole)
5 Mirror scale to eliminate parallax errors while reading the
measuring value
6 Table with dB values which must be added to the reading value
during the dB measurement unless the lowest AC voltage
range has been selected
