Input/Output Connectors
DC OUT connector
Set the frequency weighting characteristic of the signal output from the DC
OUT connector of the unit.
1. Press the MENU/ENTER key to bring up the menu list screen.
2. Use the keys to select [I/O] and press the MENU/EN-
TER key. The menu list screen appears.
3. Use the keys to select [DC OUT] and press the MENU/ENTER
key. The DC OUT setting screen appears.
4. Use the keys to select [MAIN] and press the MENU/ENTER
key.
The main channel signal is output to the DC OUT connector located
at the bottom of the unit as a signal passing through the frequency
weighting, rms detection and logarithmic compression processes. The
signal is a level-converted DC signal having the frequency weighting
and time weighting characteristics set by the unit.
Output voltage: 2.5 V, 25 mV/dB
(at Output Level Range Upper)
Example:
When the output level range upper is set to
120 dB, 2.5 V ±50 mV is output at an input
of 120 dB.
Output impedance: 50 Ω
Load impedance: 10 kΩ or more
Suitable cable: Output code CC-24 (BNC - mini plug cable)
The performance of other cables is not guaranteed.
If the “DC OUT” is set to OFF, the signal is not output.
Important
Using this feature will reduce battery life by
about 25 percent.
