FG-7000TA Digital Torque Gauge

Operation Manual

| Operators should wear protection such as a mask and gloves in case pieces or components break away from the unit under test.

Whether the unit is ON or OFF, DO NOT exceed the capacity of the sensor. NEVER exceed 120% of the rated capacity, or the torque sensor will be damaged. At 110% of the rated capacity the display will flash a warning.

If mounting FG-7000T Series Digital Torque Gauges, use M4 mounting screws with a maximum insertion depth of 7 mm into the gauge. Hand tightens mounting screws, DO NOT use tools. Do not use damaged clamp.

Measure in line torque only. DO NOT attempt to measure forces at an angle to the sensor – damage to sensor may result.

Do not attempt to repair or alter this instrument. Warranty will be voided and damage to the unit may result.

Use and store within the stated temperature and humidity ranges, or damage and failure may result.

If not using this instrument for extended periods of time, remove the batteries to prevent potential battery leakage from causing product damage.

DO NOT use tools to over torque the connection adapter. Hand-tighten only so damage does not occur.

The FG-7000TA Series digital torque gauges provide testing flexibility with their external torque sensor input. Torque sensors with the adjustable clamp adapter are immediately recognized when connected to the display base. Units are available for your specific testing needs in 1 N-m (9 in-lb) 5 N-m (44 in- lb) & 10 N-m (88 in-lb) capacities. The adjustable clamping mechanism enables flexible test size operation from approximately 0.56 to 2″ (14 to 50 mm) diameters. Four selectable modes of operation include: Track mode for live readings, Peak mode for displaying the maximum reading, First Peak where only the initial peak is recorded once a decrease is sensed and Preset which initiates user-programmed tolerance alarms for go/no go testing. The display has two selectable operations, numerical view with directional bar graph or graphical view with directional bar graph. In graphical view when alarm tolerances are set, the process is plotted in relation to the upper and lower limit graph lines. Combined with the go/no go icons, a simple pass/fail determination is recognized. These high-tech instruments can data log a reading at the push of a button for simple data acquisition or be set to continuous data storage. Data can be viewed on the screen, sent to the optional printer, or loaded to be analyzed and graphed on the free software program. The 1,000 point memory with definable groups allows for multiple tests to be recorded and easily separated upon loading. In addition, the comparator output can be set up for integration of the instrument into a quality system for repetitive testing such as on a production line. The large back-lit, 180° auto-reversible display, CW/CCW directional bar graph, combined with the dual labeled key pad allows for usage of the gauge in various positions while still being able to easily view and operate. These various features make the FG-7000T the ideal torque instrument for various applications such as closing or opening analysis of containers, valves and door hardware, failure or destructive torque testing, or almost any torque testing requirement involving incoming quality inspection, finished goods testing to R&D.

Figure 4-7a Figure 4-7b

(1) Calibration Point
(2) Current Value
(3) Standard Input Value

Load a standard force on the gauge. Wait a moment for the force to stabilize. The current value (2) should equal the standard force applied.

If the values do not match, press “ZERO” and “MODE” keys to correct the standard input value (3).

Press “MENU” to enter the next calibration point. After any of the calibration points have been completed, touch “LOG” to exit the calibration mode. Then save the calibration or discard by pressing “Yes” or “No”.
