The digital handheld compression force measurement tool is a small, simple, multi-function, and high-precision push and pull test measurement instrument, which is widely used in electronic appliances, construction hardware, fire equipment, power machinery, scientific research institutions, and other industries. Like the digital force gauge push pull tester, the handheld force gauge for springs has a high resolution, fast sampling speed, and is easy to read. And this compression force gauge or sensor is a new high-precision push-pull test instrument.

As one type of handy force gauge, the handheld digital compression force tester has an advanced microprocessor, which can timely access the changes of built-in sensor data, continuous correction of the zero point, linearity, and temperature drift of the meter, to ensure the high accuracy of the compression force tester over a long period of time. The digital handheld compression force gauge meter made by our testing and measuring instruments companies has a compact and reasonable instrument structure, and the digital display is intuitive and clear. The withdrawable external battery can be replaced at will in imported cases.

How to Use Digital Compression Force Tester?
1.Choose the model
This series force gauge has a variety of models that can be selected, different models corresponding to different ranges and resolutions, as shown in a table on the back cover of this manual. Select the appropriate model based on practical need before use. DO NOT exceed the capacity of the gauge, or it may damage the force gauge forever.
2. Choose measuring heads
In order to complete the test work conveniently, the force gauge is equipped with a variety of measuring heads(adapters). Select the appropriate measuring heads according to the actual need.

3. Power on/offTouch for 2 seconds to power On or Off.After switching the instrument on, you should check the model whether it is you want.Check Battery Icon. If the power is low, should be recharged.4. TestingAfter completion of the test preparation, testing can be done.4.1 Measuring headsSelect the appropriate measuring head, and install it in the gauge's measurement axis. Tighten it by hand, without the use of tools. Do not use a deformed or damaged measuring head.NOTE: Do not use tools to vigorously tighten the measuring head, otherwise it will damage the force gauge.4.2 UnitsThe force gauge has a variety of measurement units, select the appropriate unit of force. Under the measure interface, press the Menu key to enter the menu.4.3 Test ModeThis series force gauge has 3 kinds of measurement test modes that can choose. interface.You can select a Measure Mode by touchingunder the measure interface, Or can change it in menus.Track: The real-time measuring mode, under this mode, press the zero keythe force gauge will be cleared (remove tare).

Peak: Peak readings will not change until a higher value is measured. Under this mode, touch the zero key the force gauge will update the display immediately.Auto-Peak: In this mode, the gauge displays a peak value of force in a fixed duration. The duration time can be set in menus.4.4 Tolerance LimitThe tolerance limits can be set for GO/NG measurement also.If you set the alarm on and a valid limit, The iconwill be displayed for within limit, lower than lower limit or exceed upper limit.4.5  ZeroingTouchto clear the force gauge in track mode for removing the tare.5. Hand-held or MountingThe force gauge is a portable Instrument, you can do the testing hand-held, or you also can install the force gauge on the test stand so as to obtain accurate measurement results. There are 6 M4.0 mounting screw holes on the back， which can be fixed on the test stand.NOTE: The depth of the mounting hole is 8.0mm, please choose the appropriate screws, screw into the depth of the force gauge shall not be greater than 7mm.6. StorageMeasured results can be stored in the force gauge so that you can review or print them later.Under the measured interface, touchto save value measured, and the save iconwill be displayed.7. Browse and PrintingThe values saved in memory can be reviewed in the Browse function. The data in memory can be printed into a report.
