Inspection/Standard Accessories

If upon delivery shipping damage is detected, do not operate the unit. Notify shipping carrier immediately for damage claim instructions. Refer to nameplate and record serial number for future reference. Items included with the DART are:

• (1) Carrying case

• (1) Standard adapter set (hook, chisel, flat head, notched head, cone head, extension rod)

• (1) Inch adapter (metric - English thread)

• (1) Hanger

• (1) RS-232C cable (FGV-X series only)

• (1) AC charger/adapter

Features and Benefits

Shimpo’s DART series digital force gauges offer many features and benefits, including:

• 1,000 Hz update rate for capturing highest peaks

• Aluminum construction provides exceptional durability

• An ergonomically designed digital instrument to fit perfectly in the palm of your hand

• Single touch, measure force in lb, Kg and N (oz/gram for 0.5X, 1X,2X) engineering units

• When gauge is placed on a test stand or if the hanger is used, display may be reversed with push buttons so that it can be read right side up.

• High accuracy ( ±0.2% F.S. ) is ideal for QC inspection and process control

• RS-232C and Analog output (FGV-X series only)

• Inch adapter for converting our Metric thread to an English thread. If your fixtures are English threaded, please use this adapter.

Safety Precautions

Do not operate or store instrument in the following places: explosive areas; near water, oil, dust, or chemicals; areas where temperature is above 104°F (40°C).

When not in use, place gauge back in its case to prevent damage due to accidental drop etc. With a little care you can have an instrument that will provide service for many years.

Do not disassemble or repair unit while in operation.

Physical Features

Operation

1. Charge the batteries for approximately 18 hours before using the gauge (Batteries come discharged from the factory). The BAT indicator is on when batteries are charging, off when the batteries are fully charged.

2. Hand tighten appropriate attachment to unit’s measuring shaft (do not use a wrench or any other device to tighten the attachment).

3. Press POWER and release. The unit will display model name in small display and capacity in main display and then will show some zeros with the last one or two digits changing to some random numbers. Also the unit of measurement (lb (oz), Kg (g) or N) will appear above the digits and stay as long as the instrument is on.

Change Display Units

To change the display units, just press UNIT and the units will change every time the button is pressed.

lb ! oz (0.5X, 1X, 2X models only) ! N ! Kg (g) !

Reverse the Display

If unit is used with the hanger or mounted on a test stand and the display must be reversed, follow this procedure:

2. Low Battery Indicator

3. Peak Indicator

Factory Setting

The FGE/V-X will revert to factory setting when the gauge is first powered on. Consult the “Function Setting” section to customize these default settings.

1. Press POWER and hold it; display will go blank.

2. Press and hold UNIT.

3. Release POWER while you are still holding UNIT; display is still blank.

4. Press POWER once more and release it while still holding UNIT. At this point you should see the display reversed.

5. Release UNIT; the display stays in that mode.

To go back to normal mode repeat steps 1 through 5.

Select Average or Peak

If you want to measure force in real time (average) the display will show only the digits and units of the force being measured. If you want to measure “peak” force:

1. Press PEAK; the word PEAK will appear in the upper left corner of the display. (If you need a minus peak, press PEAK again.)

2. The display will freeze after capturing the peak force.

3. Press ZERO to cancel previous peak and continue with your tests.

If you want to go back to average mode press PEAK again. The word PEAK will disappear from the display.

NOTE: It is very important that you measure forces (tension or compression) that are in line with the measuring shaft and not at any angle (see fig. 1). Failure to observe this directive will damage the instrument. Also, after the gauge is positioned and ready to take a measurement (with the proper attachment in place) tare the unit by pressing ZERO. To clear the display for another measurement (in PEAK mode), press ZERO.

Tension Measurement

To measure tensile force, use the hook attachment. The display will show the force measured and a minus sign () will appear on the left of the display (to the left of the digits).

NOTE: To display no sign (plus) for tensile force, consult the “Function Setting” section.

Compression Measurement

To measure compression force, use the flat head attachment. No sign will appear on the left of the display during a compression measurement.

NOTE: To display minus sign (-) for compression force, consult the “Function Setting” section.

Low Battery

When battery charge is low, LO BAT will appear on the display indicating the batteries need to be charged. Charging time of fully depleted batteries is approximately 18 hours when the unit is off. The adapter/charger automatically shuts off when the battery is at full charge to protect the battery.

Note: The adapter/charger can be used to power the unit during battery charging, but will lengthen charging time.

External Device Communications

When operated with the appropriate output cable, the FGV-X offers output capabilities.

Overload

Even though each model is able to withstand an overload of 200% of its rated capacity, caution should be exercised that this does not happen, otherwise the sensor will be damaged. To protect the gauge and/or the sample under test when a motorized stand or some other device is used in conjunction with the gauge, two overload output OC NPN transistors are available to be used to disconnect power when the overload condition reaches 120% of the gauge’s rated capacity. One transistor is for tension and the other for compression. See figure 2.

Auto Power Off

If the gauge is on and there is no activity for 10 minutes, the unit automatically powers off to conserve battery charge. PWR appears above the display digits to notify that there is 1 minute before power off. If the adapter/ charger is powering the gauge, auto power off function becomes inactive.

NOTE: To modify the auto power off function, consult the “Function Setting” section.

Tracking Function

A tracking function has been introduced to check and compensate for temperature drift. When measuring very minute forces (a few ounces or grams) and at a very slow rate, you may want to turn off the tracking function.

To turn the tracking function off, follow the steps below:

1. Turn POWER off.

2. Press PEAK and UNIT switches simultaneously and hold, then press and release POWER (If tracking function was on, the display will show TRK OFF momentarily)

3. Release PEAK and UNIT.

The tracking function is now off. Repeat above steps to turn it on. The gauge will display TRK SET when turned on. It is a good idea to have this function on at all the times unless it is absolutely necessary to cancel it.

Analog Output

An analog output signal is available for recording purposes. The amplitude of this signal is ± 1 VDC. The voltage is positive when compression testing is performed and negative for tension. The signal characteristics are as follows:
