Best Practices:
5
1) Twisting the input leads togeth er can hel p reduce noise a nd improve
th e probe's high f requency resp onse when measuring signals. Please
view the diagram below for an example:
2) Extending the input leads may introduce more noise during measurement.
If extra extension lead is necessary, please ensure the extension leads
ar e of eq ua l length and the input signal frequency is under 10MHz.
Otherwise, measurement errors may occur.
3) While measuring a high frequency signal, don't touch the end of the
input lead with your hand or other objects. Otherwise, it may aff ec t
the accuracy of the measurement.
4) E nsure that you use an oscillo sc op e with an input imp edanc e o f at
least 1MΩ and bandwidth of at least 100MHz.
5) Turn on the oscillos co pe or e xt ernally power ed instrument and let
the probe and equipment warm up for 20 minutes.
6) When a substantial change in temperature or other circumstances affect
the accuracy of the probe's zero point, a calibration is needed: short the
input terminals of the probe, then power the probe while simultaneously
pressing the 50X(200X) and 500X(2000X) keys for three seconds.

Disconnecting the probe: First, disconnect the probe inputs from the devic e
under test, and then unplug the probe output and power input.
Use proper grounding: To avoid an electric shock, all de vi ce s t ha t req ui re
grounding must be connected to earth ground. Before making co nn ections to
the input or o utput termi nals of the probe, ensure that the test instrument is
properly grounded if necessary.
Measurement safety: Always be aware of the voltage rating of the prob e an d
the measurement accessories you are using and of the maximum amplitude of
the signal you intend to measure. Never apply a potential th at exc eeds t he
vo ltage r at ings of th e pro be and/ or its accesso ri es to a voi d dam agin g th e
product and creating a hazardous situation.
Only qualified personnel should perform service on this product.
Do not touch exposed connections and components when power is present.
If an over-range condition occurs, please disconnect power and signal input
from the probe immediately.
Do Not Operate in an Explosive Atmosphere.
Do Not Operate in Wet/Damp Conditions.
Keep Product Surfaces Clean and Dry.
Please read this manual carefully before use!
Introduction
1
The Micsig DP series of high voltage differential probes are designed for
the sa fe measuremen t of high voltag e and floa ting voltage signals. Tw o
models with 100MHz bandwidth are available, each capable of two different
attenuation ranges: 500X(2000X) for a maximum te st voltage of 1300V
(5600V) and 50X(200X) for amaximum test voltage of 130V(560V).

1) Powering the probe:
Connect the USB input of the probe to the USB port of the oscilloscope
or a suitable USB power source.
2) Connecting the probe to the oscilloscope:
Connect the probe output BNC to the oscilloscope channel input.
Note: make sure the oscilloscope is properly grounded if necessary.
3) Set the appropriate attenuation r ange accordin g to the measured
voltage.
4) Connecting the input to the device under test:
Using the appropriate input accessory, connect the probe to the device
under test to start the measurement. If the attenuation range ind icator
flashes (indicating over-range), ple as e i mm ediately disconnect t he
power and input.
5) Set the measuring instrument.
