READ CAREFULLY BEFORE
USING FOR THE FIRST TIME
Your instrument is equipped with a NiMH battery. This technology offers several
advantages:
Long battery charge life for a limited volume and weight.•
Possibility of quickly recharging your battery.•
Signicantlyreducedmemoryeffect:youcanrechargeyour•
battery even if it is not fully discharged.
Respectfortheenvironment:nopollutantmaterialssuchaslead•
or cadmium, in compliance with the applicable regulations.
After prolonged storage, the battery may be completely discharged. If so, it must
be completely recharged.
Your instrument may not function during part of this recharging operation.
Full recharging of a completely discharged battery may take several hours.
NOTE: In this case, at least 5 charge/discharge cycles will be necessary
for your battery to recover 95% of its capacity.
To make the best possible use of your battery and extend its effective service life:
Only use the charger supplied with your instrument. Use of•
another charger may be dangerous.
Only charge your instrument at temperatures between 0° and 40°C.•

The charging conditions.•
Do not dispose of the battery pack with other solid waste. Used batteries
must be entrusted to a qualied recycling company or to a company
specialized in processing hazardous materials.

CHAPTER 1
INTRODUCTION
Warning
These precautions for use are imperative when using the machine. Failure
to comply with these instructions may lead to electric shocks, explosions or
re.
The operator will consult these instructions whenever the• symbol
is displayed.
If you use this instrument in a way which is not specied, the protection •
which it provides may be compromised, putting you in danger.
When removing or inserting the battery and/or SD card, ensure that the•
measuring leads, sensors and power cord are disconnected. The unit
must be disconnected and powered down.
The unit must not be used if the “battery/SD card” housing is absent,•
damaged or incorrectly tted.
The safety of any system incorporating this instrument is the responsi-•
bility of the system assembler.
For your safety, only use the leads and suitable accessories delivered•
with the instrument: they comply with the norm IEC 61010-031 (2002).
When the sensors or accessories of lower voltage and/or category are
connected to the unit, these lower voltages and/or categories become
applicable to the entire set.
Before using the PowerPad• ®always check that the leads, sensors and
accessories are in perfect condition. If anything appears damaged
(even partially) it must be repaired or scrapped.
Comply with the specied environmental conditions.•
It is advisable to use individual protective safety devices when the•
environment in which the unit is used require them.
This unit must be used for CAT IV installations, for voltages that do not •
exceed 600VAC/DC in relation to the ground (per IEC standard 61010-1)
or for voltages that do not exceed 1000V for CAT III installations. Never
use voltage networks or categories greater than those mentioned.
Only use power cords and battery packs supplied by the manufacturer.•
They have specic security mechanisms.
Comply with the limits of the accessory or sensor safety mechanisms. •
Do not keep hands close to unused terminals.
Certain current sensors cannot be inserted and removed from bare •
conductors under a dangerous voltage: consult the sensor’s manual
and comply with handling instructions.

1.1 International Electrical Symbols
Signifies that the instrument is protected by double or reinforced insulation.
CAUTION - DANGER! Read the User Manual.
Risk of electric shock. The voltage at the parts marked with this symbol may
be dangerous.
Refers to a type A current sensor. This symbol signifies that application around
and removal from HAZARDOUS LIVE conductors is permitted.
Refers to a type B current sensor. Do not apply around or remove from HAZARD-
OUS LIVE conductors without additional protective means (de-energizing the
circuit or wearing protective clothing suitable for high voltage work).
USB socket
The CE marking guarantees conformity with European directives and with
regulations covering EMC.
The trash can with a line through it means that in the European Union, the
product must undergo selective disposal for the recycling of electric and
electronic material, in compliance with Directive WEEE 2002/96/EC.
1.2 Definition of Measurement Categories
CATI: Measurement category I corresponds to measurements taken on circuits
not directly connected to the network.
CATII: Measurement category II corresponds to measurements taken on cir-
cuits directly connected to the installation.
Example: measurement for electrodomestic units, portable tools and
analogue devices
CATIII: Measurement category III corresponds to measurements on building
installations.
Example: measurement on distribution panels, cabling, etc.
CATIV: Measurement category IV corresponds to measurements taken at the
source of low-voltage installations
Example: metering and measurements on overvoltage protection
devices.

1.3 Receiving Your Shipment
NOTE: After receiving your PowerPad®, charge and discharge the instru-
ment one or two cycles to ensure the proper level display of the battery
indicator.
Make sure the contents shipped are consistent with the packing list. Notify your
distributor of any missing items. If the equipment appears damaged, le a claim
immediately with the carrier and notify your distributor at once. Save the damaged
packing container to substantiate your claim. Do not use equipment which is dam-
aged or appears to be damaged.
