P5210 Instructions 1
Getting Started
This section describes the P5210 High Voltage Differential Probe and
gives instructions on how to install and functionally test the probe.
Features and Accessories
The P5210 High Voltage Differential Probe shown in Figure 1
provides a safe means of measuring circuits with floating high
voltages. The probe outputs a low-voltage, ground-referenced signal
for display on instruments with the TEKPROBE interface (or any
oscilloscope or other measurement instrument when used with the
Tektronix 1103 TekProbe power supply).
The P5210 High Voltage Differential Probe probe allows clear and
accurate measurements of high-speed transitions and provides
excellent rejection of common-mode signals. Both inputs have high
impedance and low capacitance. Because of these features, the probe
can safely and accurately measure the fast voltage transients in
switching power devices without risk of damage.
Other applications for the P5210 High Voltage Differential Probe
include testing high-voltage motor control circuits and line
connected circuits in switch-mode power supplies.

Getting Started
2P5210 Instructions
The probe has a number of design features to protect you from high
voltage. This protection extends up to the full input rating of the
probe.
HThe probe head and input cables are double insulated.
HThe control buttons and probe housing are non conductive and
isolated.
HThe probe housing is internally shielded with a connection from
the shield to earth ground through the output cable.

WARNING. To avoid shock or burn hazard, use only the standard
accessories or accessories that are rated for the application. Use the
P5210 High Voltage Differential Probe accessories with this product
only.
Keep your fingers behind the finger guard on the probe body
whenever possible to reduce the risk of a shock from the circuit under
test.
Differential Inputs. The inputs are CAT II rated to a
maximum of 2,200 VRMS between either input and
earth ground. They are also rated for a maximum
difference of 4,400 VRMS CAT II between the inputs
with less than 5,600 V (DC + peak AC) between the
inputs.
Attenuation Range. In the raised position the range
button sets the attenuation to 1,000X. In the lowered
position the range button sets the attenuation to 100X.
Use the 1,000X position for measurements up to a
maximum of 4,400 VRMS CAT II. Use the 100X
position for better signal resolution on connections
below 440 VRMS CAT II.
Overrange Indicator. The overrange indicator lights red
if the voltage of the input signal exceeds the linear
operating range of the probe. When this happens, the
signal on the probe output does not accurately represent
the signal on the probe input.

P5210 Instructions 5
ON Overrange Beeper. In the raised position the overrange
button sets the overrange beeper to sound whenever the
overrange indicator lights.
Bandwidth Select. In the raised position the bandwidth
button sets the full bandwidth (50 MHz). In the
lowered position the bandwidth is restricted to
approximately 5 MHz.
Input Leads. The input leads of the differential probe
connect to the probe tips. The connectors are 4 mm
insulated banana plugs and are double insulated for
safety.
NOTE. Use only accessories that are rated to the
maximum input voltage under test.
TEKPROBE Interface. The TEKPROBE interface
provides power, signal, and probe characteristic data
transfer.
If your oscilloscope does not support the TEKPROBE
interface, you can use the optional 1103 probe power
supply as an effective interface. Contact your local
Tektronix representative for more information.

Zero Adjust. Use the zero adjust to set the probe output
to the zero reference point prior to making measure-
ments. Use the adjustment tool provided.
6-32 Probe Tip
Finger
Guard Probe Body. The probe body is designed for personal
safety, ergonomic comfort, and signal fidelity. The
body is rated for the maximum input voltage of the
P5210 High Voltage Differential Probe.
The probe tip is a 6--32 threaded post that accepts the
hook tips provided with the probe.
The finger guard provides protection when the hook
tips are not being used. Keep your fingers behind the
finger guard whenever possible to reduce the risk of a
shock from the circuit under test.
Use only accessories that are rated for the application.
Substitution of other accessories may create a shock or
burn hazard.
Keep the probe body and accessories clean to reduce
the risk of shock due to surface conduction. Refer to
page 17 for cleaning instructions.

P5210 Instructions 7
Small Hook Tip. Use the small hook tip for making con-
nections to small conductors such as component leads.
The hook tip is rated for the maximum input voltage of
the P5210 High Voltage Differential Probe.
Install the small hook tip by sliding it over the body of
the probe and screwing it onto the threaded probe tip.
To use the tip, hold the probe body and pull the tip
shield back. Hook the tip onto the circuit and release
the shield.
Large Hook Tip. Use the large hook tip when working
with larger components such as the bolt terminals and
bus bars typically found in power distribution equip-
ment. The hook tip is rated for the maximum input
voltage of the P5210 High Voltage Differential Probe.
Install the large hook tip by sliding it over the body of
the probe and screwing it onto the threaded probe tip.

Getting Started
8P5210 Instructions
To use the tip, hold the probe body and pull the tip shield
back. Hook the tip onto the circuit and release the shield.
Soft Case. The soft case protects the probe and allows
you to hang the probe near the point of measurement.
Install or remove the case by opening the access flaps
on the back.
When not in use, coil the leads and secure them with
the strap on the back. Use one of the loops to hang the
probe on a storage hook or utility belt.
Color Marker Bands. When you are using more than one
probe, the bands enable you to quickly distinguish
between probes and the channels they are connected to.
To use the marker bands, attach one band near the
probe head and the matching band near the compensa-
tion box.
For a complete list of replaceable accessories and part ordering
information, refer to the service manual that accompanies this
product.

P5210 Instructions 9
Installation
Install the P5210 High Voltage Differential Probe as follows:
1. Connect the output of the probe to the TEKPROBE input of the
oscilloscope or other measurement instrument. Make sure the
measurement instrument is properly grounded.
NOTE. Use the 1103 TEKPROBE Power supply if the instrument does
not have the TEKPROBE interface.
2. Select the proper range setting. For higher resolution and less
noise when measuring signals below 440 VRMS, switch the
attenuation to 100X. If the overrange indicator lights or flashes,
use the 1,000X setting or the output signal may not be accurate.
3. The probe output is adjusted to zero at the factory. Adjust the
probe output to zero only if you need to measure small differen-
tial voltages. Follow steps a through c to make the adjustment.
a. Let the probe warm up for at least 20 minutes.
b. Set the probe to the desired attenuation (100X or 1,000X).
c. Connect the input leads of the probe together. Insert the
adjustment tool in the access hole of the compensation
box and adjust the probe to the zero reference point.
If you are using this probe for the first time, read the General Safety
Summary on page iii, and Operating Basics on page 11 for important
safety information.
