button pressed when switching on
the meter. A clock symbol then does not appear in the display.
AC/DC output
The testo 816 meter has an AC/DC output with the following
specifications:
AC
: 1 V RMS at end-scale deflection
Output impedance approx. 100 Ohm
Output signal through standard 3,5mm jack connector
(see figure below).
Note: If the meter measures in the Auto Range function,
the output signal corresponds to the automatically
selected measurement range.
DC
: Output 10mV/dB
Output impedance 1 kOhm
