Xtester-VC300 new Vibration Calibrator, Digital vibration meter for Calibration
Overview
Xtester-VC300 Vibration Calibrator can be used to calibrate vibration accelerometer, velocity and proximity transducer and also a vibration measuring instruments. Standard sine signals at frequency 10, 20, 40, 80, 160, 320, 640 and 1280 Hz can be generated from this Vibration Calibrator. The amplitude of the, acceleration, velocity and displacement, can be defined through potentiometers and shown on digital displays. Either horizontal or vertical vibration can be generated by this Vibration Calibrator. GJX-3 Vibration Calibrator combines sine signal generator, power amplifier, standard transducer and a shaker in one and features a small volume, high accuracy and easy operation. It can be used either in laboratory or on site. |

Difference between VC300, VC500i and VC600
VC300, VC500i and VC600 are very similar devices with only a few differences on the frequency control:
Frequency (Hz) | Frequency Selection | Signal External input and adjustable | |
Xtester-VC300 | 10, 20, 40, 80, 160, 320, 640, 1280 | Only at discrete frequency points | No |
Xtester-VC500i | 10, 20, 40, 80, 160, 320, 640, 1280 1Hz to 10kHz | 1. At discrete frequency points only when use signal generator inside 2. Continuously adjustable when use external signal generator, frequency range may be from 1Hz to 10kHz. | Yes |
Xtester-VC600 | 1-1280 | Continuously adjustable | No |
