1 SAFETY
Caution!
Note the dynamometer’s capacity before use and ensure that the capacity is not exceeded.
Producing a force greater than 200% of the dynamometer’s capacity can damage the internal load
cell. An overload can occur whether the dynamometer is powered on or off.
The following safety checks and procedures should be performed before and during operation:
1. Never operate the dynamometer if there is any visible damage to the AC adapter or the
dynamometer itself.
2. Ensure that the dynamometer is kept away from water or any other electrically conductive liquids
at all times.
3. The dynamometer should be serviced by a trained technician only. AC power must be
disconnected and the dynamometer must be powered off before the housing is opened.
4. Always consider the characteristics of the sample being tested before initiating a test. A risk
assessment should be carried out beforehand to ensure that all safety measures have been
addressed and implemented.
5. Wear eye and face protection when testing, especially when testing brittle samples that have the
potential to shatter under force. Be aware of the dangers posed by potential energy that can
accumulate in the sample during testing. Extra bodily protection should be worn if a destructive
failure of a test sample is possible.
6. In certain applications, such as the testing of brittle samples that can shatter, or other applications
that could lead to a hazardous situation, it is strongly recommended that a machine guarding
system be employed to protect the operator and others in the vicinity from shards or debris.
7. When the dynamometer is not in use, ensure that the power is turned off.

2 POWER
Caution!
Do not use AC adapters other than supplied or instrument damage may occur.
The dynamometer is powered either by an 8.4V rechargeable battery or by an AC adapter (input jack is
located in the left side of the housing).
If the AC adapter is plugged in, an icon appears in the lower left corner of the display, as follows:
If the AC adapter is not plugged in, battery power drainage is denoted in a five-step process:
1. When battery life is greater than 75%, the following indicator is present:
2. When battery life is between 50% and 75%, the following indicator is present:
3. When battery life is between 25% and 50%, the following indicator is present:
4. When battery life is less than 25%, the following indicator is present:
5. When battery life drops to approximately 2%, the indicator from step 4 will be flashing.
Several minutes after (timing depends on usage and whether the backlight is turned on or
off), a message appears, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. An audio
tone will sound and the dynamometer will power off.
The dynamometer can be configured to automatically power off following a period of inactivity. Refer to
the Other Settings section for details.
Battery life is approximately 24 hours with the backlight off, or 7 hours with the backlight on. To change
the battery, loosen the two captive screws on the back side of the housing and separate the two housing
halves. A foam strip separates the battery from the PCB, as shown in the illustration below:
Ensure that the foam is positioned above the battery when reassembling the housing. Exercise care when
reassembling the two halves of the housing, ensuring that internal wires do not interfere.

3 MECHANICAL SETUP
3.1 Loading shaft orientation
In order to accommodate a variety of testing requirements, the orientation of the loading shaft may be
oriented in either of the two positions shown below. To change the loading shaft orientation, loosen the
two captive screws on the back side of the housing, separate the two housing halves, rotate one half 180
degrees, and reassemble. Exercise care when reassembling the two halves of the housing, ensuring that
internal wires do not interfere.
Load cell shaft up Load cell shaft down
3.2 Mounting to a plate
Although the dynamometer may be used by hand, proper mounting is important if attached to a fixture or
test stand. The round steel insert with a hole in the back of the housing is provided to withstand the load
during a test. A mating dowel pin should be used (see illustration below). An additional two holes are
supplied for metric screws. These holes are designed to accommodate screws in order to hold the
dynamometer in place. The screws must not be used for load bearing purposes. Failure to use a dowel
pin properly can result in a hazardous situation.
3.3 Mounting attachments to the dynamometer
The dynamometer’s threaded loading shaft is designed to accommodate attachments with female
threads. To mount n attachment, gently thread it onto the shaft. Attachments may not orient in a parallel
manner when tight. In such cases, do not over-tighten, or damage will occur. Loosen the attachment to
the desired position, and use in this manner, or use a jam nut to prevent the attachment from rotating.
Use two wrenches to tighten a jam nut; the second wrench should engage the flat section of the load cell
shaft. This is to prevent loosening of the loading shaft, which can lead to damage.

7DIGITAL FILTERS
Digital filters are provided to help smooth out the readings in situations where there is mechanical
interference in the work area or test sample. These filters utilize the moving average technique in which
consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer
contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection
of 1 will disable the filter since the average of a single value is the value itself.
To access digital filter settings, select Filters from the menu. The display appears as follows:
Two filters are available:
Current Reading –Applies to the peak capture rate of the instrument.
Displayed Reading –Applies to the primary reading on the display.
Available settings: 1,2,4,8,16,32,64,128,256,512,1024. It is recommended to keep the current reading
filter at its lowest value for best performance, and the displayed reading filter at its highest value for best
visual stability.
