II. What is the TNP Torque Meter?

The TNP torque meter is a portable static torque measuring device that can be
used as a quality assurance tool for various applications that require
measurement of turning (both opening and closing) and twisting.

Some of the industries that can utilize this
equipment are:

• Pharmaceutical

• Food/ Beverage

• Cosmetic products

• Packaging

Equipped with internal rechargeable batteries, the
TNP can operate as a portable DC powered
device or thru the universal AC adapter.
Designed with a small footprint it can easily be transferred to maximize use
around the shop floor or the laboratory.

The programmable HI-LO set points make this unit ideal for pass-fail testing in a
production environment.

Do not test products that are filled with liquid as the TNP
torque tester is not protected from liquid spills.

III. Product Features

• High Accuracy: ± 0.5% F.S.

• Wide Torque Range: 0.5Nm, 2Nm, 5Nm and 10Nm (available models)

• Adjustable Sample Size: 10-190 mm diameter (0.39”-7.48”)

• Selectable units for measurement:

TNP-0.5 : mN-m, N-cm, g-cm, lb-in
TNP-2, 5, 10 : N-m, N-cm, kg-cm, lb-in

• Large Display: Easy to read digital display

• PC Output: USB interface with add in software (Digitorq)

• Flexible Power: Can run with built in rechargeable NiMH batteries or

Universal AC adapter

• Selectable Measuring Modes: Captures Peak Opening, Closing and
Average (CCW, CW)

• Portable: Small foot print, compact design, space saver

• Programmable HI and LO set points for Pass-Fail testing

• Store up to 1000 values into memory

Extended Description

• Units/Status indicator – located on the upper part of the display this
shows the current units of measure selected for the torque meter. It also
serves as a sub display under function mode (F01, F02, F03, etc.)
Example: “OVR” indicates an overload condition the TNP went over its
rated capacity. “PWR”, the auto power off feature is set this indicator
serves as a 1 minute warning before the unit turns off.

Overload

before it turns off.

• Main display/Set up Values – shows the measured value in four digits
including decimal places. While under function mode, this displays the
options for each setting.

• Direction Indicator – indicates direction of applied torque based from F04
setting (Please see sign orientation information from function mode table).
By default, closing indicates a negative “-“values; Opening “no sign”.

5

• Battery Indicator – shows the status of the TNP internal battery. “LO
BAT” appears on the display to indicate a low battery status. “BAT” is
shown when the TNP is charging. This indicator disappears when the
battery is fully charged or when the AC adapter is disconnected from the
TNP. It is important that the battery be cycled properly to achieve the
maximum life from it.

VIII. Operation

Pretest Checklist:

Determine the size of the sample to be tested. Adjust the 4 jig on the testing
table accordingly. Center the sample and use the knob to secure the sample in
place (clockwise to tighten the jig to the sample material).

It is important to make sure that all the jigs are flush to the moving brackets.
Each one of these jigs has set pins which slides into place inside the grooved
brackets.

Measuring Modes

on how to select the right mode for testing.

Pressing the Mode key toggles through the mode available from the TNP, LED

OPEN and CLOSE modes are PEAK Values captured by the TNP, these values
are not real time values, and are retained on the display until one of the following
occurs, the Zero/RST key is pressed or a higher peak value is detected (which in
this case, replaces the current value detected).

MEAN is real time value based on the average data captured in 1000 samples
per second.

The maximum display update for all modes is 8 times/second.
This update rate can be adjusted by changing F02 from function mode
(See section VII - Values available 1, 2, 4, 8 times/second).

Comparator Function

This compares the measured value to the upper and lower limits entered under
function mode for HI and LO limits.
If both HI and LO limits are set to “0000” this feature is not available
(deactivated).
The following conditions are valid under comparator mode:

• HI>LO

• HI=LO (HI Red LED indicator will be lit on the Comparator LED indicators).

Utilizing this feature makes it an ideal tool for quality assurance checks.

Example: HI is set to 100 and LO is set to 50. Based from the conditions met
the corresponding LED will light up (HI (Red LED), GO (Green LED), LO (Red
LED)).

Test 1 = 105 HI
Red LED
Test 2 = 45 LO
Red LED
Test 3 =65, GO

LO:ON

From the previous example any values greater than 100 will light up the HI red
LED.
Any values lower than 50 will light up the LO red LED.
Values measured in between these values (100<X<50) will give a GO green LED
indicator.

12

How to change the HI and LO values from the TNP torque meter?

• To set the HI and LO limits from the TNP torque meter access the function
mode. (See section VII).

• Power off the torque meter

• Press and hold the Zero/RST key then power on the torque meter.

• Continue to hold on the Zero/RST key until the main display shows F01

• Press the Zero/RST key until the main display shows HI limit

• Using the Recall key we can increment the highlighted digit from 0-9.

• Press the Mem key to move from left to right or to the next digit.

• Entering values that are invalid the display will blink momentarily indicating

wrong values entered to the HI and LO limits. (HI>LO, HI=LO).
After entering the LO limit value and pressing the Zero/RST button the
torque tester will go back to normal operation.

13

XI. Zero adjustment / Tare the TNP

Taring or zeroing the value of the TNP initialize the torque meter to zero.
This function is performed by pressing Zero/RST button on the front panel. In
OPEN and CLOSE modes this zeros out the Peak values measured.

It is essential that the TNP be zeroed out before performing another
test. This ensures that the TNP is properly initialized and no
additional values are added to the measurement.

XII. Saving Data in Memory

Data can be stored in the TNP meter by pressing the Mem key. This feature is
only available in OPEN and CLOSE measuring modes.
NOTE: In MEAN or Average mode the Mem key has no function.

XIII. How to recall stored Memory

Select Open or Close Mode, press the Recall key and the display will indicate the
number of data stored in memory.

Press Recall key second time to access the following information.

• AVERAGE Value

• MAX Value

• MIN Value

• Stored data (Data order of recall is based from the last data stored in

memory)

Displays Max Values after pressing Recall

To access the stored measured value use the Recall key to scroll thru the values.
(This will be after the MIN value is displayed). The display will flash two sets of
numbers, the first number indicates the memory ID and the second number is the
value stored on that memory ID.

NOTE: The order of values is from the last data stored to the first data stored. To
review previous values shown, scroll through the values using the Recall key.

XIV. Clearing Stored Data

There are two types of memory clear available on the TNP torque meter.

• Single memory clear

• Clear all memory

Single Memory Clear

Single clear refers to erasing the stored data manually from the torque tester. The
erase process starts from the most recent to the very first data stored.

Clearing data that is within the set cannot be accomplished by a
single memory clear. The TNP does not allow the user to select the
memory to be deleted. (jump out of sequence).

How does it work?

First select from Open or Close Modes (Mean or average mode data cannot be
stored).
Press the Recall key to access memory, the first display you see will indicate the
number of data stored in the torque tester and the last value saved.

Example from the picture above shows 3 data is saved (003) and the last value is

12.6. Pressing the Zero/RST button, the last data is eliminated (CLr will appear
on the screen). Pressing the Zero/RST button again deletes the next data stored
in the TNP torque meter.

17

Here is a flowchart of how the single clear works.

(Appear 1 sec.)

When there is one last data, the last data is cleared by pressing Zero/RST
key. After that, “nonE” is displayed at main display for 2 seconds, then the
display returns to measuring mode as shown below:

After all the data are erased pressing the Zero/RST button returns the display to
normal measuring condition.

Clear all Memory

Clear all Memory or erasing all stored data in memory is possible by doing the
following.

• Power off the TNP torque meter

• Press the Mem key and continue to hold this key while powering the

torque tester. The TNP will initialize itself. You will see the model capacity
displayed on the front panel then followed by the message “nonE”. This
indicates that all data stored in memory have been erased or cleared.
