Checkline WTT-110 Manuel d'utilisateur télécharger pdf

The WTT-110 Pull Tester has been calibrated in accordance with factory

proceedures and is certified to perform within the stated accuracy

specifications. Assuming the unit is handled with care and operated as

detailed in this manual it should remain accurate for an extended time

period. If however, it is subjected to forces that exceed its maximum range

or if it is not properly cared for, it might need to be recalibrated.

It is recommended that the calibration is verified at least on an annual

basis and more frequently if feasible. Normally, instruments of this type

go out of tolerance from one day to the next and rarely on a regular

periodic basis.

A calibration procedure is provided in this manual, however it should only

be performed by individuals properly trained for this type of service and

with the appropriate certified standards (known weights or secondary

force measuring system such as a load cell, etc.).

1. Remove the lever by unscrewing it in a counter-clockwise

direction and move the Wire Clamp assembly out from

the path of the hanging sample.

2. Position the WTT-110 in a vertical position so that the

keypad & display are at the top (refer to photo). Be sure

to secure it so it can not topple over when the weight is

attached.

3. Using a heavy-duty monofilament (fishing line), wire or

similar, suspend a 50 Kg weight from one of the teeth

on the wire terminal fixture by hooking a loop of the

material over the selected tooth.

4. Temporarily, remove the weight and follow the

Re-Calibration Procedures shown on side 2.

Re-Calibration Set-up

Make sure that the WTT-110 is well secured in the

vertical position. Select a material that is strong

enough to support 50 Kg of weight.
