Automatic balancing recorder.
This is an automatic balancing type recorder that can be widely used for recording noise and vibration levels, frequency analysis, as well as for measuring the characteristics of various acoustic devices and transducers, and for linear recording of voltage. It can produce sharp records with a dedicated pen. 【External Control of Operations】 The operation/stop of the pen and paper feed, marker recording, and paper feed speed can be controlled externally. 【Paper Feed Control Measurement】 The paper feed speed can be increased to make the record more readable only while the measured noise (or vibration) level exceeds a set level. This is effective for measuring discontinuous noises such as train noise or aircraft noise, and it helps prevent unnecessary consumption of recording paper. 【6 Power Supply Options for Use Anywhere】 There are six types of power sources available: two types of dry batteries, two types of rechargeable batteries, a car battery, and an AC adapter, allowing it to adapt to any power supply situation.

basic information
Applicable Standards JIS C 1512:1996 "Level Recorder for Noise Level and Vibration Level Recording" Input Section Input Impedance: 50k Unbalanced Voltage Required to Indicate Maximum Scale: AC Input 0.2–10Vrms DC Input 0.5–25V Recording Section Recording Method: Automatic Balancing Method Frequency Range: When recording range is 25dB or 10dB: 1Hz–100kHz (tolerance ±1dB) When recording range is Linear: 1Hz–100kHz (±10% of full scale) When recording range is 50dB: 1Hz–20kHz (tolerance ±0.5dB, but 1dB at 1Hz) Rectification Method: True RMS Rectification Response of Recording Pen: Exponential Response Type Recording Pen Speed: 400mm/s or more Paper Feed Control Measurement: Usable when recording range is 50dB When input exceeds the set level, the paper feed speed becomes 10 times the set paper feed speed (however, this is invalid for set values of 3, 10, 30mm/s and external synchronization) Set Levels: Three-stage switching at 10, 15, 20dB.
