3.2 Operation Steps
3.2.1 Mounting Sensor
3.2.1.1 Sensor(Acceleration or Velocity) installation: put the M5 screw, sensor fixed on the table in turn. Different sensors, sometimes need to use the corresponding conversion screw;
3.2.1.2 The eddy sensor installation: Put the benchmark on the test plate, the eddy sensor fixed suite in sequence;
3.2.1.3 When calibrating, place the calibrator stable as possible. When change the sensor, need to turn off the power supply. After the calibration, the sensor should be removed for avoiding the sensor is left for a long time on the table.
3.2.2 Cable Connection
3.2.2.1 The calibrator can measure and display the value of measured sensor output , so the output of these sensor such as charge mode ,IEPE mode and Voltage mode can be connected to the socket of signal input socket(BNC);
3.2.2.2 For the output of 4-20 mA sensor, please connect the signal to "4-20 mA" terminal, internal calibration instrument is illustrated below.
3.2.2.3 For eddy displacement sensor, the calibrator can offer the power to the preamplifier; The green terminal is -24VDC, the black one is 0V; And the output of preamplifier connect to the signal socket of the BNC ;
3.2.2.4 If hope to measure the output signal of adjusted sensor, please check the socket of sensor output signal–(BNC); For this signal can be adjusted automatic by the calibrator, so the output signal should be amplified X1 or X10.
3.2.2.5 Connect to AC Power: Please confirm the AC power supply should be 220 V / 50 Hz;
3.2.2.6 If hope to operate by PC, connect the calibrator to PC by one USB cable.
3.2.3 Operation Setting
After checking cables and sensors be fixed correctly, turn on the power and the LCD will display as follows:
