Measurement range (for an accelerometer of charge sensitivity 1.0–9.99pc / m/s2) | Acceleration | 1, 10, 100, 1000, 10000 m/s² 5 range |
Velocity | 3 Hz to 1, 10, 100, 1000 cm/s 4 range 10 Hz to 1, 10, 100, 1000 cm/s 4 range 30 Hz to 0.1, 1, 10, 100, 1000 cm/s 5 range | |
Displacement | 3 Hz to 1, 10, 100, 1000 mmp-p 4 range 10 Hz to 0.1, 1, 10, 100, 1000 mmp-p 5 range 30 Hz to 0.01, 0.1, 1, 10, 100 mmp-p 5 range | |
H function | Value of acceleration detected after passing 2 kHz to 15 kHz bandpass filter then detected and processed by 1 kHz low pass filter. Unit is the same as of acceleration. | |
Filter response | Lower cutoff frequency : Off (1 Hz), 3, 10, 30 Hz Higher cutoff frequency : 300Hz, 1, 3, 10 k, Off (100 kHz) Cutoff : -18 dB Butterworth | |
Indication | rms : Mean square value EQP : Equivalent peak estimated from average value PEAK : Peak value P-HOLD : Held max. peak value | |
Level watching function | Alarm level step : 1 Step for every channel Setting : 0 to 110 % for every range Alarm output : 1a Relay contact output / ITTL level output for each individual channel Contact capacity : DC30 V 0.5 A, AC120 V 0.5 A | |
Output | Waveform : voltage 0 to ± 5 V (load 10 kΩ or higher) Level output : voltage 0 to ± 5 V (load 10 kΩ or higher) calibration output : 80 Hz Sine output | |
Ambient temperature / humidity | 0 to +40゚ C / 85 %RH or lower (non-condensing) | |
