AttachACVoltage signal output to an external recorder

Size : 260 × 87 × 36mm

Electrical Specifications:

Obvious Show Device	18mm LCD,3 1/2 digits
Measurement functions	dB(A&C frequency weighting), Time weighting(Fast, Slow), Max hold, Max hold reset, AC output
Test range	3 ranges ( 30 - 70 dB,60 - 100 dB,90 - 130 dB )
Solution Analyze Degree	0.1 dB
Fine Indeed Degree	Time weighting & frequency weighting meet IEC 651 type 1, calibrating input signal on 94 dB (31.5 Hz to 8 kHz), the accuracy of A weighting is specified as following: 31.5 Hz - ± 1.5 dB, 63 Hz -± 1.5 dB, 125 Hz - ± 1 dB,250 Hz - ± 1 dB, 500 Hz - ± 1 dB, 1 kHz -± 1 dB,2 kHz - ± 1 dB, 4 kHz - ± 1 dB, 8 kHz - + 1.5 dB to -3 dB
Frequency weightingwork	Characteristics of A & C.
	A weighting - The characteristic is simulated as "Human Ear Listing" response. Typical, if making the environmental sound level measurement, always select to A weighting.
	C weighting - The characteristic is near the "FLAT" response. Typical, it is suitable for checking the noise of machinery (Q.C. check) & knowing the sound pressure level of the tested equipment
The test frequency range	31.5 Hz to 8,000 Hz
School Positive Device	B & K (Bruel & kjaer), multi-fuction acoustic calibrator, model : 4226
Microphone types	Electric condenser microphone.
Microphone size	1/2 inch standard size.
Range selection	30 to 70 dB,60 to 100 dB,90 to 130 dB,40 dB on each step,with over & under range indicating
Time-weightedwork (Fast / Slow)	Fast - t= 200 ms, Slow - t = 500 ms, * "Fast" range is simulated the human ear response time weighting. "Slow" range is easy to get the average values of vibration sound level. * The "Fast" & "Slow" time weighting range are designed to IEC 651 type 2 requirement
Correction methods	Build in external calibration VR, easy to calibrate on 94 dB level by screw driver. Internal oscillation system, 1 KHz sine wave generator
Output signal	AC output - AC 0.4 Vrms corresponding to each range step.
Output terminal	3.5 phone output terminal is provided for connection with analyzer, level recorder, tape recorder.
