The DTMX is supplied with six (6) dip switches permitting the user to select
desired Display Update Rate, Memory Mode and Data Output Type as detailed
below.
To access the dip switches, the Thumbpiece and Slide Guide Plate must be
removed. Refer to access instructions below.

8.00 CALIBRATION
The DTMX is factory calibrated by taking a series of measurements with
known weight standards suspended from Factory Calibration Standard
Materials. The built-in microprocessor uses this calibration data with a com-
plex formula to calculate a calibration curve which takes into account material
rigidity, material thickness and orientation of use. The factory calibration
works well in most cases. However, if the process material to be measured dif-
fers significantly from the Factory Calibration Standard Materials (see table
below) or if the application requires the highest accuracy possible, perform a
Field Calibration Adjustment (refer to Section 8.20) or return the gauge to the
factory for optional Special Calibration.
Note: When ordering a Special Calibration, please supply a 10' sample of the
process material for calibration purposes.
