利用金屬的彈性制成標有刻度用以測量力的大小的儀器，謂之“測力計”。測力計有各種不同的構造形式，但它們的主要部分都是彎曲有彈性的鋼片或螺旋形彈簧。當外力使彈性鋼片或彈簧發生形變時，通過杠桿等傳動機構帶動指針轉動，指針停在刻度盤上的位置，即為外力的數值。數字測力計在醫藥品、化妝品、食品、包裝、汽車、電氣、電子、機械等各種行業都被廣泛使用，是產品制造、品質管理、研究開發中的測力工具。有一種具有完善的數據管理功能的新型測力計，通過USB接口可以跟電腦連接，能夠進行1000次/秒的快速峰值測量，可以設定上限值和下限值，判斷產品是否合格。也可以與測力計支架配套使用，能夠得到高精度的測量。

The Checkline FGV-XY force gauge delivers industry-leading value with an extensive list of features including USB output, reversible display and a rugged metal housing. Each gauge is supplied as a complete kit with several screw-on adapters providing a complete force testing instrument for use in a wide variety of industries. All models include built-in memory for 1000 values, easily downloaded via the USB data output to a PC using the software.

美國Check-Line FGV-XY最能體現其工業級水準，配置豐富，包括USB輸出，可視性高顯示屏和堅固地金屬外殼。每個FGV-XY都會配套不同的螺紋接頭，使得測力計可以用在不同的工業應用領域。所有的型號都內置存儲，輕松下載，并通過軟件向電腦USB輸出數據。

Includes software allows force values can be transferred in real time or batch downloaded after testing is complete. In addition, RS-232C and analog outputs are also supplied providing the FGV-XY with maximum flexibility for data transfer and recording. Additionally, measurement statistics are automatically calculated and stored and can be recalled to the display for viewing or can be downloaded. Statistics include maximum, minimum, average and standard deviation.

在測量完成之后，FGV-XY可通過軟件實時或者分批下載測量值，選配RS-232C和模擬量輸出功能后，測力計可以更加靈活地傳輸和讀取數據。在測量過程中，測力計會自動計算統計數據，然后存儲，這樣使用者可以事后翻開記錄或者下載之前的測量數據。測力計會統計值，最小值，平均值和標準偏差。

The FGV-XY provides is suitable for use in numerous industries & applications including incoming quality inspection, finished goods testing, R&D as well as on wire pull testing, wire crimps, trigger pull, brake pedal, aerospace, ceramic, springs, food ripeness, corrugated paper strength, blister pack, medical component, muscle strength, ergonomic testing, adhesives, syringe plunger, needle sharpness and many more.

FGV-XY適用于很多種行業與應用，包括質量檢測，成品測試及研究與開發，例如線拉力測試，電線彎曲，扳機引力，剎車踏板，航天，陶瓷，彈簧，催熟食物，瓦楞紙板強度，罩板包裝，醫療用品，肌肉強度，環境測試，粘合劑，注射器柱塞，針銳利度等等。
