9
dB Output: Provides logarithmic output of +1.50 V DC, at a
meter reading of +10 dB, into a 100 K⍀ load; a
lower impedance will not affect the meter read-
ing. The response time of this output is set by the
“Fast-Slow” setting. The exponential-time-aver-
aging time constant is per ANSI S1.4 - 1983, para-
graphs 6.2 and 6.3: Slow is 1000 milliseconds,
and Fast is 125 milliseconds. The recommended
plug is Switchcraft’s #850 (0.097" diameter).
10. Power Requirements: One 9-volt alkaline battery, NEDA 1604A (or
equal) will typically provide 40 hours of continu-
ous operation.
11. Temperature Range:
Operating Temperature: -10°C to +50°C.
Storage Temperature: -40°C to +60°C with the battery removed.
12. Temperature influence: Typically 0.015 dB/°C at 1kHz.
13. Operating Humidity: 0 to 90% relative humidity (non-condensing) for
a reading change of < 0.5 dB.
14. Warm-up Time: Approx. 30 seconds.
