Introduction

The PCE-SC 10 is a class 1 acoustic calibrator used for the calibration of microphones, sound pressure level (SPL) meters and other noise meters. The sound calibrator is suitable for use with type 1 or class I noise measuring instruments. This portable decibel (db) meter calibrator is easy to use in the field or in laboratories.

Applications

– Calibration of microphones, sound level meters and other sound measurement equipment
– Check the linearity of the equipment to be calibrated

Features

Complies with IEC60942:2003 Class 1, ANSI S1.40-1984 and GB/T 15173-1994
1 kHz calibration frequency for all weighting networks
Dual 94 & 114 dB sound pressure level outputs
Calibration accuracy ± 0.3 dB
Highly stable level and frequency
Easy 2-key operation
Fits 1/2” microphones and 1/4” microphones (with adaptor)
Powered by 2×AA batteries and automatic power off to conserve battery life

Information on calibration principle

The PCE-SC 10 sound calibrator is a battery operated sound source for quick and direct calibration of sound level meters and other sound measuring systems. It fits 1/2” microphones and 1/4” microphones (with adaptors). The calibration frequency is 1000 Hz, which is the reference frequency for the standardized international weighting networks. That enables you to use the calibrator for calibrating sound equipment with A, B, C, D weighting filters and linear. The calibration pressure is 94 ±0.3 dB (1 Pa) and 114 ±0.3 dB (10 Pa). The PCE-SC 10 is equipped with a feed‐back arrangement to ensure a highly stable sound pressure level. The feed‐back loop contains a reference microphone, a sound source and control circuit. The reference microphone has passed a long-term aging test and has proved to be extremely stable. The feed‐back control circuit can adjust for changes in load volume, temperature, humidity and atmospheric pressure. The calibrator gives a continuous sound pressure level when fitted onto a microphone and detects when the microphone is removed from the cavity and automatically switched off, thereby extending the battery life. When the ON/OFF light flashes, this means that the battery voltage is low. If the device stops working continuously, the batteries must be replaced.

Operation

Pull down the battery compartment cover and insert the batteries. Make sure the polarity is correct.
Switch on the calibrator as well as the device to be calibrated (On / off key). Set either 94 or 114 dB, using the change key.
Place the aperture of the calibrator on the microphone (use the adaptor if applicable).
A value now appears in the display of the sound level meter. When this value has stabilised, turn the calibration screw to adjust the value accordingly.

Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either reuse them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.
If you have any questions, please contact PCE Instruments.
