Description
The 1565-B a general purpose sound-level
meter, ideal for measurements required by OSHA and for general
noise surveys. This popular meter weights less than 1 pound, features
simple push-button operation, battery power, and a rigged ceramic
microphone. The 1565-B may be purchased alone, with an acoustic
calibrator, windscreen, and with a choice of carrying/storage
cases.

Specifications:
| Sound Level |
40 to 140 dB re 20 µN/m2 |
| Weighting |
A, B, and C. Conforms to ANSI S1, 4-1971 Type
2 and IEC651 |
| Meter |
rms response with fast and slow speeds |
| Input |
Microphone: Lead-ziconate-titanate
ceramic |
| Output |
> 1.2 Vrms behind 620Ω with meter
at full scale; will drive oscilloscope or low-impedance headphones.
Harmonic Distortion:
< 0.5% (0.1% typical) from 32 Hz to 8 kHz, C-weighted with
meter at full scale. Any load impedance may be connected. |
| Calibration |
Can be pressure calibrated at 125, 250, 500,
1000, and 2000 Hz with GR 1562 Calibrator, and at 1000 Hz with GR
1987*.
* At 125, 250, 500, 1000, 2000, and 4000 Hz with GR
1986 Calibrator. |
| Environmental |
Temperature:
-10 to 50°C operating: -40 to +60°C storage, with batteries
removed; coefficient of sensitivity ~+0.02 dB/°C at 6 dB below
full-scale meter reading.
Humidity: 0-90% RH within 0.5 dB.
Magnetic Field:
1 oersted (80 A/m) 50- or 60- Hz field causes about 45 dB C-weighted
(negligible A-weighted) indiction when meter is oriented for maximum
sensitivity to field. A 1-oersted, 400-Hz field causes about 58 db
A-wwighted indication when meter is oriented for maximum sensitivity.
Vibration:
With the microphone attached, the highest meter indications (without
interference from background noise) when the instrument is vibrated
at an
acceleration of 0.1 g, are 67 dBA at 63 Hz, 68 dBA at 250 Hz, and
70
dBA at 1000 Hz. When the microphone is replaced by an equivalent
impedance, the same test gives no meter indication. |
