The DFX II Series may be used to measure and display tensile or compressive loads at an accuracy of +0.3% of full scale. The DFX II Series may also be set to capture the peak tensile or compressive load. The DFX Series is available in four models having four different capacities and user-selectable units of measurement.
Display Layout Keypad The Chatillon DFX Series has a rubber keypad The Chatillon DFX II Series has a high resolution, containing the following keys: dot-matrix LCD, 8 lines, 21 characters. Display contrast is set at the factory and requires no ad- On/Off Key justment.
Peak 7.89 C-PK Zero and Taring The DFX II Series has a dedicated Zero key for Peak zeroing results or taring. You may tare out up to 10% of the DFX II gauge’s rated capacity. Select the Zero key to zero or tare.

Units Lock Feature The DFX II Series has an option to “lock the units”. This prevents the operator from changing the units of measure and disables the UNITS key. To enable the Units Lock feature, follow this setup procedure and depress the following keys: 1.
Selecting Language The DFX II Series allows users to select their display language. Textual information can be displayed in the following languages: English, Spanish, French, Portuguese, Chinese and German. To select your display language, follow this setup procedure and depress the following keys: 1.

Mounting Your DFX II to a Chatillon Tester The DFX II Series may be used with a Chatillon mechanical or motorized force tester. The chart shows the Gauge Adapter Plate that may be required to fit the gauge to the tester.
IMPORTANT The sensor used in your DFX II Series gauge is temperature sensitive. The gauge should be turned ON and allowed to acclimate to ambient temperature before normal use and before being calibrated. A 5 minute “warm-up” period is recommended.
