Instructions for using models M5I and M3I indicators are available in their respective user’s guides. For additional information or answers to your questions, please do not hesitate to contact us. Our technical support and engineering teams are eager to assist you.
Before use, each person who is to use Mark-10 sensors and indicators should be fully trained in appropriate operation and safety procedures.

OVERVIEW

General Overview

Plug & Test® sensors accommodate numerous force and torque measurement requirements, from 0.25 to 10,000 lbF (1 N to 50 kN) of force, and from 10 ozFin to 5,000 lbFin (7 Ncm to 550 Nm) of torque. These sensors can be handheld or mounted to a fixture or test stand for more sophisticated testing requirements.
Plug & Test® sensors are used with Mark-10 M7I, M5I, and M3I indicators. They may be disconnected from one indicator and connected to another without the need for re-calibration or re-configuration. All such data is saved within a PCB located inside the smart connector.
Series FS05 and R07 sensors may also be used with Series F test frames.
The model number, serial number, and capacity of the sensor are identified in the rectangular label located on the 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.

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 M7I, M5I or M3I indicators, the accuracy of the indicator being used must be identified and taken into account, as follows:

The total system accuracy can be calculated by adding the sensor accuracy and indicator accuracy.
Refer to the following examples:

Example 1
Model MR01-100 sensor with Model M5I Indicator

This translates into a fixed error of up to: 0.25% x 100 lbF = 0.25 lbF

Example 2
Model MR50-50Z sensor with Model M3I Indicator

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 whether a M7I, M5I, or M3I indicator is being used. For example, a Series R01 force sensor will display finer resolution when connected to a M5I indicator than when connected to a M3I indicator. Resolution information is shown in the following sections.

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 when 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.

SETUP

The Plug & Test ® connector must be inserted into the receptacle of the indicator with the side marked “Plug & Test ® Technology” facing up (see Fig. 3.1). When fully inserted, the connector will lock into place with a “click”.

Appropriate orientation of the Plug & Test connector.
To release the connector, press both buttons on either side of the indicator housing (see Fig. 3.2). Pull the connector completely out of the indicator by holding the curved aluminum section. DO NOT pull on the cable or strain relief.

Press both buttons on either side of the indicator housing to release the Plug & Test connector.

Operating humidity:
Weight:| 40ºF – 100ºF [5ºC – 38ºC] 96% max. (non-condensing)
From 1.4 lb [0.6 kg]

Calibration
Calibration should be performed in a vertical orientation, especially for sensors with capacities of 50 ozFin [35 Ncm] or less. Horizontal orientation subjects the sensor to side loads resulting from the weight of the chuck and attachments. Such side loads can be significant enough to skew the readings out of tolerance.
The illustration below depicts a recommended vertical setup:

For further calibration instructions, refer to the indicator’s user’s guide.
