Clearance requirements
The unique common mode voltage range of the measurement system allows it to be used in the presence of high frequency/high voltage
common mode signals. It is important to observe all precautions while using this product.
WARNING: Electrical shock can occur while using this measurement system. The system is intended to isolate the operator from
hazardous input voltages (common mode voltages); the plastic case of the probe head and the shield on the probe tip do not
supply safe isolation. Maintain the safe clearance from the probe head and probe tip while the measurement system is connected
to the energized circuit as recommended in this document. Do not access the RF Burn Hazard Zone while taking measurements
on a live circuit.
The following figure shows the components of the measurement system and the potential RF burn area when working with hazardous
voltages. The RF burn area of 1 m (40 in.) is indicated by the dashed lines surrounding the probe head.

WARNING: Risk of RF burns. Refer to the following derating curve to identify the danger areas. To avoid RF burns, do not operate
the probe within limits of the gray shaded area in the graph.
WARNING: There is a risk of burn from elevated temperatures on the tip when continuous wave or high duty cycle burst common
mode signals are between about 10 MHz and 50 MHz. This causes the tip ferrites to dissipate significant power at voltages lower
than found on the following graph. To avoid the burn risk, keep the tip temperature at 85°C (185°F) or lower by limiting the applied
common mode voltage and/or duty cycle, lowering the ambient temperature, and/or applying forced convection airflow.
