IEC Measurement Categories BumbleBee®
Definitions and Examples (Clause 6.5.2)
Measurement Category I Definition: Measurement category I is for measurements performed
on circuits not directly connected to a mains supply.
Examples: Measurements in circuits not derived from a mains supply
and specially protected ( internal ) circuits derived
from a mains supply. In the latter case, transient stresses
are variable; for that reason it is required that the transient
withstand capability of the equipment is made known to
the user.
Measurement Category II Definition: Measurement category II is for measurements performed
CAT II on circuits directly connected to the low voltage
installation.
Examples: Household appliances, portable tools and similar
equipment.
Measurement Category III Definition: Measurement category III is for measurements
CAT III performed in the building installation.
Examples: Measurements on distribution boards, circuit breakers,
wiring including cables, bus-bars, junction boxes, switches,
socket-outlets in the fixed installation and equipment for
industrial use like for example stationary motors with per-
manent connection to the fixed installation.
Measurement Category IV Definition: Measurement category IV is for measurements
CAT IV performed at the source of the low-voltage installation.
Examples: Electricity meters and measurements on primary over
current protection devices and and ripple control units.

IEC Pollution Degrees BumbleBee®
Definitions (Clause 3.5.6 )
Pollution Degree 1 No POLLUTION or only dry, non conductive POLLUTION.
NOTE The POLLUTION has no influence.
Pollution Degree 2 Only- non conductive POLLUTION. Occasionally, however, a temporary
conductivity caused by condensation must be accepted.
Pollution Degree 3 Conductive POLLUTION occurs or dry, non-conductive POLLUTION occurs
which becomes conductive due to condensation which is to be expected.
IEC Safety Symbols
The following symbols may appear on the product or in this instruction manual:

Safety Information BumbleBee®
To avoid personal injury and to prevent fire or damage to this product or products connected to it, review and
comply with the following safety precautions. Be aware that if you use this probe assembly in a manner not
specified the protection this product provides may be impaired.
Only qualified personnel should use this probe assembly.
Use only grounded instruments.
Do not connect the probe ground lead to a potential other than earth ground. Always make sure the probe and
the measurement instrument are grounded properly.
Connect and disconnect properly.
Connect the probe output to the measurement instrument and connect the ground lead to earth ground before
connecting the probe to the circuit under test. Disconnect the probe input and the probe ground lead from the
circuit under test before disconnecting the probe from the measurement instrument.
Avoid unnecessary stress.
The small electrical components of the probe are sensitive to shock and impact. Avoid any unnecessary kinetic
stress to the probe like throwing, falling and strong vibrations.
Observe probe and probe accessory ratings.
Do not apply any electrical potential to the probe input which exceeds the maximum ratings of the probe or the
accessories connected to it. In a combination always the lower rating / measurement category applies to both
probe and accessories connected to it.
Make sure to comply with the voltage versus frequency derating curve on page 8.
Keep away from live circuits.
Avoid open circuitry. Do not touch connections or components when power is present.
Do not operate with suspected failures.
Refer to qualified service personnel.
Indoor use only.
Do not operate in wet/damp environment. Keep product surfaces dry and clean.
Do not operate the product in an explosive atmosphere.

Safety Information BumbleBee®
BumbleBee has a rated Input Voltage of 2000 V Measurement Category I or 1000 V CAT III.
Note that the max. input voltage rating of the probe decreases as the frequency of the applied
signal increases. (see Voltage Derating on page 9)
See the relevant section of this manual for further information on maximum input voltage, voltage derating and
definitions of relevant IEC Measurement Categories (CAT).
Grounding the Probe
Connect the probe to the oscilloscope input and connect the ground lead to earth ground before performing any
measurements.
BumbleBee is designed for ground-referenced measurements only.
About BumbleBee
BumbleBee® is a 400 MHz, 2 kV Measurement Category I or 1 kV CAT III High-Voltage Differential Probe,
that can be used with every instrument having 50 ΩInput Impedance.
The probe is very effective in power device evaluation such as measurements in IGBT circuits used in the design
of motor drives, switching power supplies and frequency converters. Especially 1700 V IGBT modules for
inverters and converters.
BumbleBee is also very effective in fast transient measurements with bandwidths of up to 400 MHz.
Measurments at GaN and SiC modules as part of new semiconductor techniques prot from that in particular.
It provides a 4 Mode Attenuation, which allows higher resolution measurements. The probe provides overload
indicators for each input channel as well as for the output. That makes it easy to observe, that the differential
probe is working in the specied range.The probe also provides an active offset correction in a range of ± 4 V,
related to the output voltage, with a resolution of 15 Bit.
These and many other functions can be remotely controlled with the PC-Software "PMK Probe Control".
The Software is free and included in the scope of delivery of PMKs PS-02 and PS-03 Power Supplies.
The intuitive gracal user interface makes all interactions with BumbleBee clear and easy.
Measurement Princible
The differential probe consists of two attenuators, which are differentially matched. The Voltage measurements
of these attenuators is conducted ground-referenced. The read voltages are provided to a differential amplier,
where the differential voltage is amplied according to the choosen attenuation.
The Output Signal is fed over a driver stage to the 50 Ω Input of a measuring device.

Handling for Firmware v.3.5 and above BumbleBee®
General Information:
Adjust the Input Coupling of the Measuring Instrument to 50 Ωbefore connecting the probe to it.
After connecting the power supply you hear a short triplet of signals from the buzzer and the LEDs of the key-
board blink. You may start with your measurements or adjust attenuation and offset correction.
User Default:
Settings of the BumbleBee Probe are saved in real-time, with no need to actively save or recall at any time.
Global Offset:
By pressing "Set" you can switch between the set global offset position and zero. While in setup menu, this
function is not available. Also with set "Hold Overload" an occuring Overload Event must be cleared before
switching offset Zero position is available.
Factory Settings:
By pressing both Buttons "1+2" together while in Setup Menu, the probe resets to factory settings. Hold both
buttons down for 5 Seconds; wait until you hear a differing signal.
Setup Menu:
By holding the "Set" Button down for five seconds you reach the Setup Menu of BumbleBee.
(Overvoltage-indicator LED of the output blinks green)
The focused Menu Item is indicated by the attenuation LEDs. This focus can be altered with the buttons "1" and
"2". Use the Buttons "5" and "6" to alter settings of the focused Menu Item. Pressing the "Set" Button again
ends the menu.
Keylock:
If no key is pressed 10 seconds after opening the menu the keypad will be locked.
Press the "Set" Button again to release it.
Setup Menu starts with item "I", indicated by the unlit LED 500:1. Change the item with
the buttons 5 and 6. Move between menu items with the buttons 1 and 2.
Overload indicators (LEDs B) show the state of an item. Green for On / Yes, unlit for
Off / No. In the following LEDs are marked as x = unlit and o= lit.
Menu Item I: ( x o o o )
For channel identification the following colors (modes) are available:
unlit, white, yellow, cyan, pink, blue, green, red;
Menu Item II: ( o x o o )
In case of detected overvoltage at input or output channel, the Overload Buzzer gives an audible signal and can
be turned on- and off with Button "5".
Additionally the Hold-Overload Buzzer can be activated with Button "6".
In case of detected overvoltage the "Set" Button has to be pressed to confirm and carry on.
Menu Item III: ( o o x o )
The Key Buzzer can be activated here, giving audible feedback when any Button on the keypad pressed.
Menu Item IV: ( o o o x )
Offset Synchronisation can be turned on and off here.
