Caution!

Note the torque tester’s capacity before use and ensure that the capacity is not exceeded. Producing a torque greater than 150% of the tester’s capacity can damage the internal sensor. An overload can occur whether the tester is powered on or off.

The tester is designed primarily for the testing of torque tools, although other items can be tested as well. Items that should not be used with the tester 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 load.

The following safety checks and procedures should be performed before and during operation:

1. Never operate the tester if there is any visible damage to the AC adapter or the tester itself.

2. Ensure that the tester is kept away from water or any other electrically conductive liquids at all times.

3. The tester should be serviced by a trained technician only. AC power must be disconnected and the tester 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.

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 tester is not in use, ensure that the power is turned off.

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 torque has been reduced to a safe level).

Five operating modes are possible with the TT02 torque tester. 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 Clockwise (PCW)

The primary reading corresponds to the peak clockwise reading observed. If the actual torque 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 Counter-clockwise (PCCW)

Same as above, for counter-clockwise readings.

5.4 First / Second Peak (2PK)

Displays first and second peaks for the same measurement direction. This function is used to identify the true peak before tool rotation reaches a hard stop, causing an artificial spike in torque. This mode will only appear if enabled in the First / Second Peak menu.

5.5 Break Detection (BRK)

Arms the tester for automatic data output, automatic zero, and/or automatic data storage upon tool slip or click, as configured in the Break Detection menu. This mode will only appear if enabled in the Break

Detection menu.

6 CHANGING THE UNITS

UNITS

ozFin * lbFin lbFft Ncm Nm

The tester will always power on with the unit selected in this sub-menu.

Series TT02 Digital Torque Tool Testers User’s Guide

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:

DIGITAL FILTERS

(1 = Fastest)

Current Reading 1 Displayed Reading 1024

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.

Note: 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 POINTS

8.1 General Information

Set points are useful for tolerance checking (pass/fail) and triggering an external device in process control applications. Two limits, high and low, are programmed in the tester, and the primary reading is compared to these limits. The results of the comparisons are indicated via on-screen indicators as well as through the three outputs provided on the 15-pin connector, thus providing “under”, “in range”, and “over” signaling. These outputs can be connected to indicators, buzzers, or relays as required for the application. On-screen indicators are described in the next sub-section.

8.2 Configuration To configure set points, select Set Points from the menu. The screen will appear as follows:

Series TT02 Digital Torque Tool Testers User’s Guide

SET POINTS Upper Disabled * Upper Enabled

5.00 Lower Disabled * Lower Enabled

3.50

Either one, two, or none of the set points may be enabled. To toggle between the clockwise and counterclockwise directions, press the DIRECTION key.

If two set points have been enabled, they are displayed in the upper left corner of the display. If only one set point has been enabled, the word “OFF” will appear in place of the value. If no set points have been enabled, the upper left corner of the display will be blank.

8.3 Set Point Indicators

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 load

limit (NO GO HIGH)

– the displayed value is between the limits (GO)

– the displayed value is less than the lower torque

limit (NO GO LOW)

Note: Set point indicators reference the displayed reading, not necessarily the current live torque.

9 DATA MEMORY AND STATISTICS

Series TT02 testers have storage capacity of 1,000 data points. Readings may be stored, viewed, and output to an external device. Individual, or all, data points may be deleted. Statistics are calculated for the data presently in memory.

Individual data points may be saved to memory by pressing the DATA key, or automatically via the Break

Detection or First / Second Peak functions, whichever is enabled. Refer to the Break Detection and First / Second Peak sections for details. Once data storage has been enabled, the data record number 0000 will appear below the primary reading in the home screen. The record number will increment each

time DATA is pressed or the automatic data storage function is activated. When memory is full the message “MEMORY FULL” will be flashed at the bottom of the display and a double audio tone will be sounded, if beeps are enabled.
