Introduction Thank you for choosing the Dillon GS series instrument. With correct use and regular re-calibration it will give many years of accurate and reliable service. The GS can measure tensile and compressive forces accurately, while being simple to use by the operator. It may be used handheld or mounted top a fixture or test stand. Software and accessories are available to make your force gauge even more versatile. Ask your distributor for additional information.
Powering the first time The GS is supplied with a set of 4 Nickel Metal Hydride AA rechargeable batteries. For safety reasons during transportation the batteries are shipped discharged. To obtain maximum battery life we recommend that you charge them with the charger/adaptor supplied for at least 14-16 hours when you first receive the instrument. Battery Indicator Battery level > 5.0 V 5.0 V > Battery level > 4.9 V 4.9 V > Battery level > 4.8 V 4.8 V > Battery level > 4.7 V Battery level < 4.
Using the GS Fitting Accessories Couple fittings directly to the load cell stem or use an extension rod. The threads are 5mm and have capacities up to 2500 N. Ensure that fixturing does nor contact the force gauge case. Ensure that anything coupled to the gauge is screwed finger-tight only. Excessive torque can damage the load cell and is not covered by warranty. Mounting to a Fixture or Test Stand Use the two 10-32 threaded holes. The distance between the holes is 2.5 inch.
To power up the gauge press the ON/OFF key. A short self-test runs during which the display will show the capacity in Newton. After the self test, providing no load has been applied to the instrument, the display will show all zeroes. This is because the gauge re-zeroes itself during the self-test routine. *If a force is applied via the load cell probe (hole at bottom of GS), the reading on display will register the applied force. *Forces may not show zero if it is moved during the self test routine.
A load indicator bar alerts the operator to how much load has been applied to the load sensor. For tensile force the indicator bar is move from right to left. For compressive forces the indicator bar is move from left to right. Zeroing the gauge During the operation of the gauge it is often necessary to zero the display – e.g. when you wish to tare out the weight of a grip, so it does not become part of the measured reading. Press and release the ZERO key.
Peak-Tension mode Press MODE key until the appeared on the display. The display will show the maximum tensile force. See Figure 3b Peak Tension symbol Figure 3b Peak Tension Peak-Compression mode Press MODES key until appeared on the display. The display will show the maximum compressive force. See Figure 3c Peak Compression symbol Figure 3c Peak Compression Resetting the gauge Press RESET key to clear both maximum registers and prepare for detecting the next maximum readings.
Saved reading to memory Any reading can be saved anytime by press MEM/ENTER key. A total of 500 readings can be stored in the database include the reading unit. Computer Control of Force Gauge gauge by sending USB commands. USB Command “m” “u” “z” “r” A computer can control the force Action Changing measure mode. Changing measure unit. Zero the gauge. Reset the gauge.
Main Menu Press MENU/ESC key to access the main menu. To move between the option listed on the main menu page, press UP and DOWN arrow keys to move the cursor. Press ENTER to select the sub-menus, activate feature and enter values. Within sub-menus UP, DOWN, LEFT and RIGHT arrow keys will also change numerical values. Press ESC to return to the main menu page.
2) PASS-FAIL the Pass-Fail feature used to set a defined acceptable maximum and minimum forces gap for measuring. It activate by setting the lower level and upper level forces limit If the forces value is within the gap level, the display will show message PASS. Any reading values outside this gap (higher or lower), the display will show message FAIL. If you activate this feature the PF symbol will display on main display.
example LOWER LEVEL = 20 N, UPPER LEVEL = 0 N Load The “OK” LED will ON. Another LED OFF. Analog Out = 2V Lower level The “LOWER” LED will ON. Another LED OFF. Time Figure 6b example LOWER LEVEL = 10 N, UPPER LEVEL = 20 N Load The “UPPER” LED will ON. Another LED OFF. Analog Out = 0V Upper level Lower level The “OK” LED will ON. Another LED OFF. Analog Out = 2V The “LOWER” LED will ON. Another LED OFF.

Press ZERO key to access the DELETE menu. DELETE ? 1) NO 2) DELETE 3) DELETE ALL Figure 7b Delete last Menu Press UP and DOWN to select the delete option , If you selected NO and press ENTER key the gauge will return to memory page. If you selected DELETE and press ENTER key the gauge will delete current saved record and return to memory page.
DIAGNOSTIC A total of overload count OVERLOAD COUNT: 2 % offset of last calibrate ORG. OFFSET : +0.4 % CUR. OFFSET : +0.4 % Figure 8 % current offset Diagnostic Menu If the % offset is between 5% - 10 % please contact your supplier to arrange a recalibration of your gauge. If the % offset is greater than 10% please contact your supplier to arrange for load cell replacement.
Measurement practice For best measurement accuracy keep the compression/tension forces in line with the force gauge. Alleviate bending loads and torque loads applied to the load cell as these can adversely affect measurement performance. Always keep the gauge below the capacity limit shown on the front of the gauge. If gauge is used above this capacity in either tension or compression, even for a short time, permanent load cell damage can result. Overload damage is not covered by warranty.
