Min/Max Integration Time
Minimum and maximum integration time for measurement of time-average levels and sound exposure
levels.
DC Output Voltage Range
0 to +3 Volt (0 to 300 dB)
V0 = SPL/100
SPL = 100*V0
or
Sensitivity = 0.01 V/dB with resolution of 0.001 V
DC Output Impedance
3650
DC Output Recommended Loads
for less than 0.4% error
A 10
DC Voltmeter represents negligible error (-0.036%).
The output resistance can be accounted for in the interface
design. For example, if a chart recorder has an input load of
10 k
the gain can be set to 1.365 to correct for the loading.
