Introduction
Thank you for purchasing the PCE-SC 42 from PCE Instruments. This sound calibrator is lightweight, compact, and easy to transport. Despite its complexity, it is simple to operate. Its robust construction ensures durability when used as intended. The calibrator is primarily used for calibrating sound level meters, sound measurement systems, and microphones, and can be used both on-site and in the laboratory.
Safety Information
Please read this user manual carefully and completely before operating the device for the first time. Operation of the device should only be performed by carefully trained personnel. This user manual is published by PCE Deutschland without any warranty.
- Immediately remove any leaked material from the device and dry it. If the spilled material is corrosive, use a suitable cleaning agent to remove it and prevent corrosion.
- Always switch off the device when not in use.
- Do not expose the calibrator to extreme environmental conditions (temperature, humidity), vibrations, mechanical shocks, dust, corrosive vapors, and strong electrostatic and electromagnetic influences for extended periods.
- Ensure that the transducer cap is always securely closed.
- If the device has not been used for 30 days, check if the battery has leaked and replace it if necessary.
- Store the device in a room where extreme temperatures, dust, corrosive vapors, mechanical vibrations, or shocks can be avoided. If you know that the device will be stored for longer than 30 days, remove the battery.
We expressly refer to our general warranty conditions, which can be found in our General Terms and Conditions. For questions, please contact PCE Deutschland GmbH.

System Description
The PCE-SC 42 sound calibrator is used to test various sound devices. If you are testing a device with a 1-inch microphone, the corresponding adapter ring must first be removed so that the microphone head sits firmly. Ensure that the microphone fits all the way into the adapter and rests on the lower edge, supporting the microphone and providing an internal seal. To perform a measurement, proceed as follows:
Components:
- Transducer Cap
- Microphone Adapter
- Battery Compartment Cover
- ON/OFF (Selection switch 94 or 114 dB)
- Battery Level Indicator (LED)
Operation
Calibration
To perform a measurement, proceed as follows:
- Set the calibrator to 94 or 114 dB using the switch. A 1000 Hz tone should be audible.
- Turn on the sound level meter to be tested.
- Carefully connect the microphone using the connecting piece. Ensure that the microphone sits firmly in the connecting piece and on the lower edge.
- After calibration, carefully remove the microphone and turn off the calibrator.
Battery Replacement
When the battery level indicator turns dark, you must replace the battery. Unscrew the lower ring (the battery compartment cover), carefully remove the switch, and remove the used battery. Then replace it with a new one.
Influence of Atmospheric Pressure and Temperature
The effects of normal atmospheric pressure fluctuations are usually negligible, regardless of location. However, altitude influences most calibrators, including the PCE-SC 42. The transducer membrane in the calibrator generates sound through its vibrations, which act on the air. If the air is thinner (at higher altitudes), a lower sound level is produced. This sound calibrator was calibrated to produce 94 dB at sea level. When the device is used above sea level, a slightly lower sound level is produced depending on the altitude. For every 2000 feet above sea level, the PCE-SC 42 produces 0.1 dB less than 94 dB. For example, at an altitude of 6000 feet, the calibrator produces only 93.7 dB. Therefore, the sound level meter should be set to 93.7 dB instead of 94 dB. Temperature influences are less than ±0.05 dB/°C, at a reference temperature of 23 °C.
