The TorqueLab
â
offers a selection of four different
Low Pass Filters
. These filters are used to
eliminate unwanted noise, most often occurring during operation of power tools.
The process of converting dynamic torque into an electronic signal using a transducer may
result in a distorted torque value due to undesirable frequencies. Different tools or applications
will generate different unwanted signals, for that reason no single filter can be specified. Our
experience has shown that a 1500 Hz filter should work with most applications, however we
recommend you, testing with different filters before validating torque values.
The filter selection is accessed through the
Set-Up
menu.
FIL 1 = 500 Hz
FIL 2 = 1000 Hz
FIL 3 = 1500 Hz
FIL 4 = 3000 Hz

This option allows the user to select the cell (transducer) to be used during operation.
Although the TorqueLab
â
features one internal cell, this analyzer can memorize and recall up to
9 external cells. The internal cell is always labeled
C.00
. Calibration data are saved under the
corresponding
Cell #
.
The
Cell
selection is accessed through the
Set-Up
menu.
You can also access this option to review current
settings for individual cells. The low capacity, high
capacity, mV/V and calibration method will be
displayed alternately in the small window.

Note:
When in

is selected, the analyzer will automatically send the torque value
to the RS 232 port before clearing (see Printing / Downloading Data section).
Note:
A value of "3333" in the small window, indicates that the cell has never been
programmed and can be available for calibration.
