P5210 High Voltage Differential Probe Service Manual

Operating Characteristics and Probing Techniques

This section explains the operating characteristics of the P5210 along
with techniques you can use to maximize the performance of the
probe.

Operating Limits

The P5210 has two operating ranges that you select with the
ATTENUATION button on the front panel: 1,000X and 100X. These
ranges set the maximum differential voltage that can be measured.

H

In the 100X position, the probe can measure differential voltages

≤

560 V (DC + peak AC).

H

In the 1,000X position, the probe can measure differential
voltages

≤

5,600 V (DC + peak AC).

Always insure that the input voltages never exceed 2,200 V

RMS

CAT II from either input to ground or 4,400 V

RMS

CAT II between

the inputs.

Overrange Detection

Differential voltage outside the operating range will overdrive the
circuitry of the probe and distort the output signal. When this
differential overrange occurs, the probe detects the condition and
lights the overrange indicator. With the Audible Overrange ON, the
probe will also emit an audible alarm.

NOTE

. Common-mode voltage greater than 2,200 V

RMS

CAT II can

distort the output signal, but the probe will not indicate an overrange
condition.

Common-Mode Rejection

The common-mode rejection ratio (CMRR) is the specified ability of
P5210 to reject signals that are common to both inputs. More
precisely, CMRR is the ratio of the differential gain to the common-
mode gain. The higher the ratio, the greater the ability of probe to
reject common-mode signals. For detailed specifications, see pages 8
and 11 in the

Specification

section.
