Proper use, operating area
The SmartCheck type 10, 100, 400 and 800 torque testers are
suitable for testing tracking and click type torque wrenches as well as
for generally measuring torques.
The SmartCheck type 10S torque tester is exclusively suitable for
testing tracking and click type torque screwdrivers.
Use in explosive areas is prohibited.
Proper use also includes observing and compliance with all of the
data in these instructions. This particularly applies to observing and
compliance with all safety instructions and warning notices as well as
the technical limit values. The DPG must only be used by personnel
trained in using the DPG.
Any other, or more extensive, use is regarded as improper, and can
lead to material damage or personal injury
Basic safety instructions
Avoiding a risk of explosion
Risk of explosion due to use of the DPG in explosive areas.
Do not use the DPG in explosive areas.
Avoiding electric shock
There is a risk of fatal accident due to electric shock if you ignore the
following safety instructions:
Never open the DPG housing.
Use only the CE-conformant plug-in power supply unit included in
the scope of delivery, see Page 15.
Prior to cleaning work on the DPG, disconnect the plug-in power
supply unit from the DPG.

Safety
9
Avoiding hazards due to improper assembly
If the DPG is not assembled properly, there is a risk of losing the
balance weight during testing. This can result in broken bones,
bruises and crushing.
Mount the DPG firmly on a worktop
Avoiding injuries due to incorrect handling
A risk of dropping occurs if an unfastened DPG is handled
incorrectly. This can result in broken bones, bruises and crushing.
Only grip the DPG at the mounting bracket.
Wear safety shoes with steel toecaps.
Avoiding hearing damage
When testing click type torque wrenches, the triggering impact
causes a sound pressure level. This can cause noise-induced
hearing loss.
Wear ear protectors in this case.
Avoiding material damage
The DPG is precision test equipment, and must be handled with the
greatest of care. Avoid mechanical, chemical or thermal effects
which exceed the stresses involved in proper use.
Soiling or moisture can lead to material damage and influence the
measurement accuracy.

Safety
10
Avoid material damage on the DPG and the torque wrenches
through the following measures:
Make sure that the torque wrenches are not damaged.
Only test the torque wrenches in the manner described in these
operating instructions.
Do not overload the DPG.
Only use the DPG for testing in the measuring range intended for
this.
Handling batteries and rechargeable batteries
Children could swallow the batteries and rechargeable batteries and
choke on them.
Make sure that batteries and rechargeable batteries are kept out of
the reach of children.
Batteries and rechargeable batteries may contain poisonous
substances which pollute the environment.
Dispose of batteries and rechargeable batteries according to the
applicable legal regulations.
Leaking batteries and rechargeable batteries may cause damage to
the DPG.
If the DPG is not used for a long time, remove the batteries or
rechargeable batteries.
Replace weakening batteries or rechargeable batteries in good
time.
Do not charge batteries.
Only use batteries or rechargeable batteries according to the data
from Page 15.

Safety
11
Warranty and liability
Warranty and liability claims in the event of personal injury and
material damage are inadmissible if they are attributable to one or
more of the following causes:
•Improper use of the DPG.
•Improper assembly, operation and cleaning of the DPG.
•Non-observance of the notes in the DPG operating instructions.
•Unauthorised modification of the DPG's properties.
•Improperly performed repairs.
Personnel training
•Only personnel which has been trained in handling the DPG or has
been familiarised by a trained person may work with the DPG.
•The personnel must be familiar with the application and handling of
torque wrenches.
•Personnel undergoing on-the-job training may only work with the
DPG under the supervision of an experienced person.
Personal safety equipment
Crushing of feet possible due to a DPG being dropped during lifting
and carrying.
Wear safety shoes with steel toecaps.
Noise-induced hearing loss possible due to the triggering impact of a
torque wrench.
Wear ear protectors.

Description
The SmartCheck type 10, 100, 400 and 800 torque testers are
suitable for testing tracking and click type torque wrenches as well as
for generally measuring torques.
The SmartCheck type 10S torque tester is exclusively suitable for
testing tracking and click type torque screwdrivers.
Use in explosive areas is prohibited.
The DPG has a stable plastic housing. The mounting bracket is
made of metal. The holes present in the mounting bracket enable
fastening in a vertical or horizontal position. STAHLWILLE
recommends fastening in a vertical position, see Page 18.
The transducer is integrated into the plastic housing. Refer to the
technical data for the respective measuring range.
The DPG's display deviation is ±1 %.
Current can be supplied using the power supply unit included in the
scope of delivery or with batteries or rechargeable batteries.
Diverse setting options are available to guarantee perfect reading of
the display.
Three modes are available:
•Track, for general measurement of torques
•Peak Hold, for indicating torque wrenches
•First Peak, for click type torque wrenches.

Fastening the DPG and preparing for
operation
Fastening the DPG
The DPG is suitable for vertical or horizontal installation. Vertical or
horizontal refers to the position of the transducer axis.
STAHLWILLE recommends fastening
the DPG the vertical
transducer axis position.
To be able to work with the DPG, it must first be fastened securely.
The base must be sufficiently solid, e.g. a worktop. The worktop
must be approx. 30 to 50 mm thick.
Use the following for fastening:
•Two cheese head screws with hexagon socket M10 according to
ISO 4762, material strength 10.9
•Two washers
•Two hexagon nuts M10
CAUTION
Broken bones, bruises and crushing during assembly.
The DPG can fall down during handling.
Wear safety shoes with steel toecaps.
CAUTION
Risk of injury due to inadequate fastening of the DPG.
The DPG can fall down.
Fasten the DPG securely.
Wear safety shoes with steel toecaps.

Fastening the DPG and preparing for
operation
18
To fasten the DPG on a worktop, proceed as follows:
Drill clearance holes with a diameter of 12 mm in the worktop.
Bolt the DPG so firmly to the base (70 N‧m) using the intended
holes that it can absorb stresses caused by the torque values to be
tested.
Secure each of the hexagon socket head screws with a washer
and a nut.
