Series 2 Digital Force Gauges User’s Guide 5. Wear eye and face protection when testing, especially when testing brittle samples that have the potential to shatter under force. Be aware of the dangers posed by potential energy that can accumulate in the sample during testing. Extra bodily protection should be worn if a destructive failure of a test sample is possible. 6.
Series 2 Digital Force Gauges User’s Guide Battery life is approximately 24 hours with the backlight on, or 92 hours with the backlight off. To change the battery, loosen the two captive screws on the back side of the housing and separate the two housing halves. A foam strip separates the battery from the PCB, as shown in the illustration below: Ensure that the foam is positioned above the battery when reassembling the housing.
Series 2 Digital Force Gauges User’s Guide 3.2 Mounting to a plate Although the gauge may be used by hand, proper mounting is important if attached to a fixture or test stand. The round steel insert with a hole in the back of the housing is provided to withstand the load during a test. A mating dowel pin should be used (see illustration below). Mounting plates on Mark-10 test stands include a dowel pin and clearance holes for the four threaded holes located near the corners of the housing.

Series 2 Digital Force Gauges User’s Guide 4.3 Menu navigation basics Most of the gauge’s various functions and parameters are configured through the main menu. To access the menu press MENU. Use the UP and DOWN keys to scroll through the items. The current selection is denoted with clear text over a dark background. Press ENTER to select a menu item, then use UP and DOWN again to scroll through the sub-menus. Press ENTER again to select the sub-menu item.
Series 2 Digital Force Gauges User’s Guide 7 DIGITAL FILTERS Digital filters are provided to help smooth out the readings in situations where there is mechanical interference in the work area or test sample. These filters utilize the moving average technique in which consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer contents. By varying the length of the buffer, a variable smoothing effect can be achieved.
Series 2 Digital Force Gauges User’s Guide CALIBRATION ENTER # CAL POINTS (1 TO 10) COMPRESSION: 5 TENSION : 5 The gauge can be calibrated at up to 10 points in each direction. Enter the number of calibration points for each direction (compression and tension). At least one point must be selected for each direction. Note: To achieve the accuracy specification of ±0.5%, it is recommended to calibrate the gauge at 5 or more even increments in both the tension and compression directions.

The following screen appears after the offsets have been calculated: CALIBRATION COMPRESSION Attach necessary weight fixtures. THEN PRESS ENTER Attach weight fixtures (brackets, hooks, etc), as required. Do not yet attach any weights or apply any calibration loads. Then press ENTER. 7.
Series 2 Digital Force Gauges User’s Guide 10. The display will appear as follows: CALIBRATION COMPRESSION APPLY LOAD 1 OF 5 ENTER LOAD: 2.000 LBF THEN PRESS ENTER Use the UP and DOWN keys to adjust the load value as required. The load values default to even increments, as indicated by the previously entered number of data points (even increments are recommended for best results).
Series 2 Digital Force Gauges User’s Guide To save the calibration information, select “SAVE & EXIT”. To exit without saving the data select “EXIT W/O SAVING”. 14. Any errors are reported by the following screens: CALIBRATION Units must be gF. PLEASE TRY AGAIN PRESS ENTER Displayed at the start of calibration if a disallowed unit is selected. LOAD NOT STABLE PLEASE TRY AGAIN Ensure that the load is not swinging, oscillating, or vibrating in any manner. Then try again.
Series 2 Digital Force Gauges User’s Guide AUTOMATIC SHUTOFF * Disabled Enabled Set Minutes 5 Select Disabled to disable automatic shutoff. Select Enabled to enable it. The length of time of inactivity is programmed in minutes via the Set Minutes parameter. Available settings: 5-30, in 5 minute increments. Note: If the AC adapter is plugged in, the gauge will ignore these settings and remain powered on until the POWER key is pressed. 9.
Series 2 Digital Force Gauges User’s Guide 9.4 Initial Mode This section is used to configure the initial mode upon powering on the gauge. To access this parameter, select Initial Mode from the menu. The screen will appear as follows: INITIAL MODE * Real Time Peak Compression Peak Tension The default value is Real Time. 9.
