ƽ Do not apply voltages that differ more than 40 V from earth ground to any
non-isolated inputs when measuring in a CAT
Ċ
environment.
ƽ Do not apply voltages that differ more than 40 V from each other to the non-isolated
inputs when measuring in a CAT
environment.
ƽ Do not apply input voltages above the rating of the instrument Use caution when
using 1:1 test leads because the probe tip voltage will be directly transmitted to the
Oscilloscope.
ƽ Do not touch the exposed part of metal BNC.
ƽ Do not insert metal objects into connectors.
ƽ Always use the Oscilloscope only in the manner specified.
ƽ Voltage ratings that are mentioned in the warning are giver as limits for "working
voltage". The represent V ac rms (50 – 60 Hz) for AC sine wave applications and as V
dc for DC applications. Overvoltage Category
refers to local level , which is
applicable for appliances and portable equipment .
