Self Calibration
The self calibration routine lets you quickly optimize the oscillo-
scope signal path for maximum measurement accuracy. You can run
the routine at anytime but you should always run the routine if the
ambient temperature changes by 5_ C or more.
To compensate the signal path, disconnect any probes or cables from
the input connectors. Then, press the UTILITY button and select Do
Self Cal to confirm that you are ready to proceed.
Probe Safety
A guard around the probe body provides a finger barrier for
protection from electric shock.
Finger guard
WARNING. To avoid electric shock when using the probe, keep fingers
behind the guard on the probe body.
To avoid electric shock while using the probe, do not touch metallic
portions of the probe head while it is connected to a voltage source.
Connect the probe to the instrument and connect the ground terminal
to ground before you take any measurements.
