Display: 3 1/2 Digit Liquid Crystal Display. Level display
indicates to 0.1 dB resolution. Annunciator is included for
Modes of Measures sound pressure level (SPL) or
Operation: maximum level (MAX).
Linear 32 to 140 dBA
Operating Range: 38 to 140 dBC
Floor: 25 dBA, 32 dBC typical
Networks: A and C
Meter Response: Slow and Fast
Microphone: Removable .52 inch (13.5 mm) diameter prepolarized condenser
(electret) microphone Model 2100 : - Type 2 accuracy
AC Output: Approximately 0 - 1 V AC RMS.
1000 ohm output impedance, 3.5 mm stereo jack
DC Output: Approximately 0 - 1 V DC RMS. Each 0.167V change equals l0dB
(1 V/60dB). 1000 ohm output impedance, 3.5 mm stereo jack
Detector: True RMS
Indicator: A '+' sign in the display indicates overload
Temperature Within 0.5dB at 23Â°C; Within 1.0dB over the
Accuracy: temperature range of -10Â°C to +50Â°C
Level Range +/- 0.7dB from 31.5 - 8000 Hz (2100)
Crest Factor: Greater than 26dB (crest factor = 20) if peak of signal does
not cause an overload. Crest factor is sufficient to handle the signal if the overload indicator
does not light.
