Specification
General specifications apply for the temperature range 5°C to 40°C with the probe connected to a
measuring instrument (oscilloscope or DMM) having an input impedance of 1M
Ω
|| <30pF. Accuracy
specifications exclude errors of that measuring instrument and apply for the temperature range 18°C
to 28°C after 30 minutes warm-up and calibration at 23°C. Specifications quoted without limits are
typical characteristics determined by design and are not guaranteed.
