1.2 Safety / Proper Usage
Caution!
Note the force gauge’s capacity before use and ensure that the capacity is not exceeded.
Producing a force greater than 150% of the gauge’s capacity can damage the internal load cell. An
overload can occur whether the gauge is powered on or off.
Typical materials able to be tested include many manufactured items, such as springs, electronic
components, fasteners, caps, films, mechanical assemblies, and many others. Items that should not be
used with the gauge include potentially flammable substances or products, items that can shatter in an
unsafe manner, and any other components that can present an exceedingly hazardous situation when
acted upon by a force.
The following safety checks and procedures should be performed before and during operation:
1. Never operate the gauge if there is any visible damage to the AC adapter or the gauge itself.
2. Ensure that the gauge is kept away from water or any other electrically conductive liquids at all
times.
3. The gauge should be serviced by a trained technician only. AC power must be disconnected and
the gauge 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.

DFG35 Digital Force Gauges User’s Guide

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 gauge is not in use, ensure that the power is turned off.
2 POWER
The gauge is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these
batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period
of storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the
receptacle on the gauge (refer to the illustration below). The battery will fully charge in approximately 8
hours.
Caution!
Do not use chargers or batteries other than supplied or instrument damage may occur.
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 will appear, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone
audio indicator will sound and the gauge will power off.
The gauge can be configured to automatically power off following a period of inactivity. Refer to the Other
Settings section for details.
If battery replacement is necessary, the battery may be accessed by separating the two halves of the
gauge. Refer to the Mechanical Setup section for details.

3 SETUP
3.1 Mechanical setup
3.1.1 Loading shaft orientation
In order to accommodate a variety of testing requirements, the orientation of the loading shaft may be set
up in either of the two positions shown below. In order 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
3.1.2 Mounting to a plate
Although the gauge 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). There are four threaded holes
located near the corners of the housing. These holes are designed to accommodate screws in order to
hold the gauge 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.
3.1.3 Mounting attachments to the gauge
The force gauge’s threaded loading shaft is designed to accommodate common grips and attachments
with female mounting holes. To mount a grip, gently thread it onto the shaft. Other mounting adapters are
also available to prevent rotation. Ensure that the grip or fixture is positioned to ensure axial load with
respect to the loading shaft of the force gauge. When using a grip, ensure that it secures the sample in
such a way that it is prevented from slipping out during a test, preventing a potential safety risk to the

DFG35 Digital Force Gauges User’s Guide
6
operator and others in the vicinity. If using a grip or fixture from a supplier other than Omega, ensure that
it is constructed of suitably rugged materials and components.
Do not use jam nuts or tools to tighten grips or attachments onto the shaft. Finger-tighten only. Anti-
rotation mounting adapters are available.
3.2 Installing the USB driver
If communicating via USB, install the USB driver provided on the Resource CD. Installation instructions
may also be found on the CD or may be downloaded from www.mark-10.com.
Caution!
Install the USB driver before physically connecting the gauge to a PC with the USB cable.
Further instructions for configuring and using the gauge’s outputs are provided in the Communications
and Outputs section.

5 OPERATING MODES
Caution!
In any operating mode, if the capacity of the instrument has been exceeded by more than 110%,
the display will show “OVER” to indicate an overload. A continuous audible tone will be sounded
(if beeps are enabled) until the MENU key has been pressed or the load has been reduced to a
safe level.
Three operating modes are possible with DFG35 gauges. To cycle between the modes, press MODE
while in the home screen.
5.1 Real time (RT)
The primary reading corresponds to the live measured reading.
5.2 Peak Compression (PC)
The primary reading corresponds to the peak compression reading observed. If the actual force
decreases from the peak value, the peak will still be retained in the primary reading area of the display.
Pressing ZERO will reset the value.
5.3 Peak Tension (PT)
Same as Peak Compression, but for tension readings.

The gauge will always power on with the unit selected.
7 DIGITAL 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 will appear 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
stability.
8 SET POINT INDICATORS
8.1 General Information
Set points are useful for tolerance checking (pass/fail). Two limits, high and low, are specified and stored
in the non-volatile memory of the instrument and the primary reading is compared to these limits.
8.2 Configuration
To configure set points, select Set Points from the menu. The screen will appear as follows:

enabled, the upper left corner of the display will be blank.
When set points are enabled, the following indicators are shown to the left of the primary reading:
– the displayed value is greater than the upper
force limit (NO GO HIGH)
– the displayed value is between the limits (GO)
– the displayed value is less than the lower force
limit (NO GO LOW)
Note: Set point indicators reference the displayed reading,
not necessarily the current live load.
9 COMMUNICATIONS AND OUTPUTS
Communication with DFG35 force gauges is achieved through the micro USB port located along the left
side of the housing, as shown in the illustration in the Power section. Communication is possible only
when the gauge is in the main operating screen (i.e. not in a menu or configuration area).
The current reading is transmitted from the gauge when the DATA key is pressed. For continuous output,
the gauge also responds to the ASCII command ‘?’ (no quotes), terminated with a Carriage Return
character or with a Carriage Return/Line Feed combination. The gauge’s responses are always
terminated with a Carriage Return/Line Feed. Any detected errors are reported back by means of error
code *10 (illegal command).
