CHATILLON DFE Series Digital Force Gauge

The CHATILLON® DFE Series marks a new era in digital force measurement. This compact, easy-to-use force gauge is designed for economy applications without compromising functionality. It is ideal for handheld applications. The DFE is available with capacities from 2 lbf (10 N) to 500 lbf (2500 N). The DFE features an integral loadcell with a measurement accuracy of better than 0.25% full scale. A large, easy-to-read, high resolution dot matrix LCD display supports a variety of standard gauge functions including normal and peak readings, high/low limits, setpoints, pass/fail results, statistical results, loadcell actuation and direction. Loads are displayed in ozf, gf, lbf, kgf and N units. The display can be inverted and displayed results may be "hidden" from the operator. The DFE gauge may be specified with or without RS232 serial communication. All DFE Series force gauges come with a carrying case, battery adapter/charger, testing accessories and NIST Certificate of Calibration with data.

Easy-to-Read Display

A large, easy-to-read 128 x 64 dot matrix display can display up to 8 lines of information. The high resolution display features contrast adjustments and can be inverted when required. The display can even be "hidden" at the press of a button. A load bargraph indicates load direction, measured load and safe load and helps prevent overloads. The integral loadcells feature mechanical overload protection at 150% Full Scale.

Single Touch Operation

The rubber keypad features dedicated and dynamic function keys. The function keys correspond to displayed options and guide the user during operation. A navigation pod lets you navigate through the menus and to scroll and change values quickly. The innovative "i" key can be used to display critical information on the gauge such as gauge capacity and resolution, battery life remaining, loadcell overload history, even service information including last calibration date, or the location of service centers.

Dependable Measurements

The DF Series features an integral loadcell sensor that delivers repeatable, accurate results. The innovative load bargraph shows dynamic load, direction of load and warns you of pending overload conditions. Smart technology in the gauge even keeps track of overload history to aide in maintenance and troubleshooting.

Comprehensive Results

The DF Series supplies you with comprehensive results that are easy to view and understand. The gauge displays:

Measured Result with Units
Operating Mode
Pass-Fail Result
High and Low Load Results
Saved Results
Statistical Calculations
- Average with MIN and MAX Results
- Cv with Average and Standard Deviation
- % Differentiation between Successive Results
- Standard Deviation based on Total Population or (n-1)

Outputs

The E-DFE Series comes standard with digital and analog outputs. RS232 outputs are supported with baud rates from 9600 to 115,600. Simply select the baud rate and whether or not you want to gauge to transmit with or without units. You may select the Mitutoyo output when communicating with a Mitutoyo device. Or, you may use the ±2V analog output to drive alarms or other ancillary devices.

Validated Calibration

The DF Series comes standard with a Certificate of Calibration with data certified to NIST. Calibration Certificates with uncertainty calculations are also offered since AMETEK is an ISO17025 accredited manufacturer.

Calibrate and Verify Status

The DFE Series incorporates flash memory and hosts a set of self-diagnostic functions for monitoring the display, keypad and electronics. Using the "i" key, you have immediate access to battery conditions, including estimated battery life remaining. You can also view loadcell status, including the number of overloads that have been applied to the gauge. Zero offset verification is standard and a step-by-step calibration procedure is built-in allowing you to calibrate your DFE gauge with certified standards.

High & Low Load or Pass-Fail Limits

The DFE Series may be configured with High and Low Load Limits or Pass-Fail Limits. Load limits allow you to establish setpoints for your testing. If the gauge exceeds a setpoint value, the gauge can provide a visual and audible alarm. You can also setup the gauge to operate as a pass-fail system. You can setup a pass-fail limit based on a limit range or on a nominal value with a % bandwidth. Based on your setup, the gauge will provide you with a Pass-Fail indication.

Advanced Testing with Statistics

The DFE Series operates in Normal and Peak modes. When peak operation is required, the display will indicate the peak reading and direction. Load values may be displayed in ozf, gf, lbf, kgf or N values.

Your DFE force gauge can store up to 10 test results in memory. Results may be viewed, cleared and used to calculate statistics. The gauge will display the number of results stored and will alert you when the memory is full.

Calculate Mean and also show you the MAX and MIN values for your calculation
Coefficient of Variation is calculated and displayed with the Mean and Standard Deviation value
Standard Deviation is calculated and displayed with the Mean and the Variance value. User may specify Total Population or Sample (n-1)
Calculate and display % Difference between consecutive test results

Simplified Setup

Menus and intelligent prompts make gauge setup fast and easy. Gauge options are presented in a "List Format". Using the navigation pod and function keys, you simply select the functions and parameters required. The gauge will guide you through the setup process. Default settings are provided and a "Quick Reset" allows you to re-establish defaults with a single key press. If your gauge features digital outputs, you can print your gauge setup parameters for record archiving or use it as a setup template for other DFE force gauges in your plant.

Personal Computer Integration

The E-DFE gauge features digital and analog outputs. RS-232 for integration with our NEXYGEN™ software and a Mitutoyo Digimatic output is available. The gauge will also supply an analog output of ±2Vdc. Use NEXYGEN software for data acquisition, graphical load v. time results, analysis and reporting. With NEXYGEN software, store an unlimited number of results for analysis.
