1.2 General Overview
From left to right: Model 3i indicator with Series R03
force sensor, and Model 5i indicator with Series R50
torque sensor
are also identified in the Information screen of the indicator.
1.3 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 either the 5i or 3i indicator, the accuracy of the indicator being used
must be identified and taken into account, as follows:
Indicator Model Accuracy
5i ±0.1% of full scale ±1 digit
3i ±0.2% of full scale ±1 digit
The addition of “±1 digit” refers to the least significant digit shown on the indicator display. This is
equivalent to one increment of resolution. The resolution may be different for some sensors depending on
whether a 5i or 3i indicator is being used. For example, a Series R01 force sensor will display finer
resolution when connected to a 5i indicator than when connected to a 3i indicator. Resolution information
is shown in the sensors’ user’s guides.
The total system accuracy can be calculated by adding the sensor accuracy, indicator accuracy, and one
count of resolution. Refer to the following examples:

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.

and connected to another without the need for recalibration or re-configuration. All such data is saved within
a PCB located inside the smart connector.

Example 1
Model MR01-100 sensor with Model M5i Indicator
MR01-100
±0.15% of full scale
This translates into a fixed error of up to:
0.25% x 100 lbF = 0.25 lbF + 0.05 lbF = 0.30 lbF
Example 2
Model MR50-50Z sensor with Model M3i Indicator
MR50-50Z
±0.35% of full scale
This translates into a fixed error of up to:
0.55% x 50 ozFin = 0.275 ozFin + 0.02 ozFin = 0.295 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.
1.4 Safety / Proper Usage
Read through the following safety instructions thoroughly before using the 5i with 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.
2 POWER
The 5i 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 indicator (refer to the illustration below). The battery will fully charge in approximately 8
hours.

Power input jack
Serial connector
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 indicator will power off.

The indicator 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 loosening the two captive screws in
the rear half of the housing and separating the two halves of the housing.

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
until the MENU key has been pressed or the load has been reduced to a safe level.
Five operating modes are possible with the 5i indicator. 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) / Peak Clockwise (PCW) - for force / torque sensors, respectively
The primary reading corresponds to the peak compression or clockwise reading observed. If the actual
load 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) / Peak Counter-clockwise (PCCW) – for force / torque sensors, respectively
Same as above, but for tension / counter-clockwise readings.
