1 OVERVIEW
1.1 General Overview
Several series sensors are available to accommodate numerous force and torque measurem ent
requirements. These sensors can be handheld or mounted to a fixture or test stand for more
sophisticated testing requirements.
Series RLC and RTQ sensors are used with Models DFG-RS5 and DFG-RS3 indicators. They may be
disconnected from one indicator and connected to another without the need for re-calibration or reconfiguration. All such data is saved within a PCB located inside the smart connector.
The model number, serial number, and capacity of the sensor are identified in the rectangular label
located on the sensor connector. The model and serial numbers are also identified in the Information
screen of the indicator. Refer to the indicator user’s guides for more information.
1.2 Accuracy and Resolution
Indicator accuracy must be combined with sensor accuracy to determine the total accuracy of the system.
Since sensors may be used with the DFG-RS5 or DFG-RS3 indicators, the accuracy of the indicato r
being used must be identified and taken into account, as follows:
Indicator Model Accurac
DFG-RS5 ±0.1% of full scale
DFG-RS3 ±0.2% of full scale
The total system accuracy can be calculated by adding the sensor accuracy and indicator accuracy.
Refer to the following examples:
Example 1
Model RLC01-100 sensor with Model DFG-RS5 Indicator
RLC01-100
±0.15% of full scale
This translates into a fixed error of up to:
0.25% x 100 lbF = 0.25 lbF
Example 2
Model RTQ-50Z sensor with Model DFG-RS3 Indicator
RTQ50-50Z
±0.35% of full scale
This translates into a fixed error of up to:
0.55% x 50 ozFin = 0.275 ozFin
Because accuracy is defined as a percentage of full scale, the fixed error is possible anywhere on the
scale from 0 to the capacity. As such, this value represents an increasingly large error as percentage of
reading towards the low end of the scale. It is, therefore, recommended that a sensor is selected with
capacity as close as possible to the expected load.
The resolution may be different for some sensors depending on which indicator is being u se d. For
example, a Series RLC01 force sensor will display finer resolution when connected to a DFG-RS5

indicator than when connected to a DFG-RS3 indicator. Resolution information is shown in the following
sections.
2 SAFETY / PROPER USAGE
Read through the following safety instructions thoroughly before using a sensor:
1. Note the sensor’s capacity before use and ensure that the capacity is not exceeded. Producing a
load greater than the indicated safe overload value can damage the sensor. An overload can
occur whether the sensor’s indicator is powered on or off.
2. In order to extend the life of the sensor, avoid repetitive shock and impact loading.
3. When moving the sensor to another location, never lift from the cable or strain relief. This can
cause damage to the sensor. Always lift the sensor housing itself.
4. Always ensure that load is applied axially with respect to the sensor.
5. Ensure that the sensor is kept away from water or any other electrically conductive liquids at all
times.
6. The sensor and indicator should be serviced by a trained technician only. AC power must be
disconnected and the indicator must be powered off before the housing is opened.
7. 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.
8. 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 sensor 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. Always wear eye and face protection whe n
testing, especially in aforementioned hazardous cases. Extra bodily protection should be worn if a
destructive failure of a test sample is possible.
9. In aforementioned hazardous situations, it is strongly recommended that a machine guarding
system be employed to protect the operator and others in the vicinity from shards or debris.
10. Sensors have threaded holes or chucks, designed for the mounting of grips, fixtures, or
attachments. If any such accessories are used, ensure they are mounted firmly to prevent a
potential safety risk to the operator and others in the vicinity. If using an accessory from a supplier
other than Mark-10, ensure that it is constructed of suitably rugged materials and components.
Similar precautions should be taken when mounting the sensor to a test stand, work bench, or
other piece of equipment.

3 SETUP
Insert the connector into the receptacle in the indicator, as shown in Fig. 3.1 below. When fully inserted,
the connector will lock into place with a “click”.
Fig. 3.1
Appropriate orientation of the connector.
To release the connector, press both buttons on either side of the indicator housing to release the sensor,
as shown in Fig. 3.2 below. Pull the connector completely out of the indicator by holding the curved
aluminum section. DO NOT pull on the cable or strain relief.
