LA-series Operating Manual Chapter 6 Calibration Description It’s advisable to calibrate the instrument since an error between setting and import/export value exists due to certain factors after a period of time (often 1 year). 6-1 Calibration Mode Two calibration modes are described below: 1. The user shall apply for calibration and then send the instruments back to the factory; this company provides ex-factory calibration report. 2.
LA-series Operating Manual Chapter 7 Maintenance, Repair and Utilization Description Maintenance and repair is divided into: maintenance by users and maintenance by factory. 7-1 Maintenance by Users 1. The users may maintain the devices without removing the instrument housing. 2. If, in the case of correct AC input power, the instrument is still disabled when PowerSwitch at left panel is “1” and Power key on the frontal panel is pressed, the fuse is already burnt.
LA-series Operating Manual 7-2 Maintenance by Factory The components shall be maintained or replaced by the manufacturer or distributor in either of the following cases: 1. After the fuse in good working order is replaced and AC power is confirmed, the instrument cannot still be opened normally. 2. The system is still maintained at open interface after startup, but it’s unable to log in operable interface. 3. Continuous operation cannot proceed in the presence of error message. 4.
LA-series Operating Manual 7-3 Troubleshooting 1. Description: please read carefully the operating instructions if certain problems or doubts are encountered when logic analyzer is employed. 2. Operating questions and countermeasures: Q1: In the event of Power on during startup, why the power indicator isn’ t highlighted, and it’s unable to display normally? Ans: Check if power cord is fastened securely, the fuse in fuse holder is normal, and AC power switch is at "1".
LA-series Operating Manual Q6: How does signal capture line and loop of every channel work normally? Ans: Connect the signal capture line of every channel to the reference square-wave of LA, and observe if the square-wave can be captured. Q7: During normal operation of circuit, can the waveform be captured after triggering? (are solid materials connected normally) Ans: Confirm if the set LA trigger state, mode and logic level conform to the specification characteristics of test circuit.
