1.2 General Overview
The 5i is a universal indicator designed for displaying
measurements from interchangeable mark-10 Plug &
Test
TM
sensors. Sensor capacities are available 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
TM
sensors are used with either the 5i or 3i
indicator. 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.
The model number, serial number, and capacity of
the sensor are identified in the rectangular label
located on the Plug & Test
TM
connector. The model
and serial numbers 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:
