P5210 High Voltage Differential Probe Service Manual
Operating the Probe Safely
Before connecting the inputs of the probe to a circuit, read the safety
information in this section, and attach the appropriate accessories to
the input connectors of the probe.
NOTE
. To avoid shock or fire hazard, use only accessories that are
rated for the application.
Minimizing Risk of RF Burn (Probe Leads)
WARNING.
To avoid personal injury, do not handle the probe leads
when the leads are connected to a source that is above the voltage
and frequency limits given in Figure 1 on page 3. The area above
these limits poses a risk of radio frequency (RF) burns.
If you need to use the probe within the risk area for RF burn, turn
power off to the source before connecting or disconnecting the probe
leads. Do not handle the input leads while the circuit is active.
Maximum Input Limits
To prevent damage to the probe, you must observe both the peak and
RMS ratings. (The rating for DC voltage is the same as the rating for
RMS voltage.) You must also observe the ratings between the
differential inputs and between each input and earth ground.
CAUTION.
To avoid damaging the input circuitry of the P5210, do not
apply voltage of more than 2,200 V
RMS
CAT II between either input
and earth ground or more than 4,400 V
RMS
CAT II between the
inputs. In addition, the peak voltage must be less than 5,600 V (DC +
peak AC) between the inputs.
Above 1.5 MHz, the voltage limit decreases as frequency increases.
See Figure 1. The input limit applies to both the 100X and 1,000X
settings.
