Wrong measurement results or poor precision:
To calculate the system errors and check the measurement results and precision, refer to the
introductions in “
Specifications
”. To reach these specifications, please:
(1) Check whether all the external devices are successfully connected and are working normally.
(2) Get some knowledge of the signal under measurement and set appropriate instrument parameters.
(3) Make measurements under proper conditions; for example, warm-up the instrument appropriately
and operate the instrument under the specified environment temperature.
(4) Calibrate the instrument regularly to reduce or avoid errors that might occur over time.
If you need a specific calibration after the stated calibration period, contact
SIGLENT
or get paid
service from authorized measurement agencies.
