This doesn’t mean charged3-5 times in a row, but rather, charged 3-5cycles under normal use.CHARGING YOUR GAUGEThe DF II Series contains a Nickle Metal Hydride (NiMh) Battery Pack that can provide up to 20 hours ofcontinuous use on a single charge.DimmingBluetooth Hours of useA Battery icon appears on the main operating display andONOFF20 hoursoperates like a bar graph. When the gauge has a fullOFFOFF16 hourscharge, the Battery icon appears full and is green. As battery power diminishes, the Battery icon will “open” and asONON16 hourspower drains, it will turn yellow to indicate a lower level ofOFFON12 hourscharge.You may view battery life remaining, by depressing the “i” key. The gauge will display the estimatedbattery life based on current usage in hours.The DF II Series gauge will alert you when the battery requires charging. The gauge will display “Recharge Required” and the battery icon will show as “opened” and red.It is best to completely drain your battery before reharging. To recharge, plug the stereo jack connectorinto the top housing. Plug the charger/adapter into your source power. Charge for 15-20 hrs to achievemaximum performance.

LOAD BAR GRAPHThe DF II Series gauge features a dynamic bar graphthat shows the force or torque being applied to thegauge.The purpose of the bar graph is to provide a visualindicator to the user when they are approaching thesensor’s capacity.The bar graph has a “T” for tension and a “C” forcompression to indicate direction of force. The bargraph fills from the centerline and changes fromgreen to yellow to red indicating proximity to thesensor’s capacity. If the DFS II-R-ND uses the STStorque sensor, the bar graph will change to show“CW” for clockwise and “CCW” for counter-clockwise.SENSOR OVERLOAD PROTECTIONThe DF II Series gauge features mechanical overloadprotection up to 150% of the sensor’s capacity.Mechanical overload protection is provided in thetension and compression direction for sensors with acapacity of 110 lbf (500N) and below.SENSOR OVERLOAD DISPLAYWhen the DF II Series gauge senses that the forceapplied is approximately 116% of the sensorcapacity, the bar graph will fill and the lowermessage line will display “OVERLOAD”.25.6TModeDisplayC-PKLBFCMoreTypical Compressive Load Display- 5.6TModeDisplayT-PKLBFCMoreTypical Tension Load Display-11.6CCWModeDisplayin-lbCWMorePASSWORD PROTECTIONThe DF II Series offers Password Protection for the unitset-up.

TheStatus will show if the function is On or Off.-If Off, Press the F1 key (On) to enable the Passwordprotection. Once enabled, the user will need to knowthe password to change the Mode, Peak Values, etc.on the unit.- If the user attempts to change a protected parameter, the unit will prompt for a password to be entered.The password is entered using the Navigation Pod(Up/Down Arrows to increment or decrement valueand Left/Right arrows to select the digit). The FactoryDefault value is “0000”.- Once the digits are entered, The Enter key ispressed to allow for changes to the unit.-The user also is prompted to use the Home key toexit if the Password is not known.- To change the Password, from the Password screen,hold the Zero key for 5 seconds and a message willshow to enter the new password.Overload16DF II Series User ManualTModeDisplayC-PKLBFCMoreOverload DisplayNOTE: Green load bar graph to 75% ofcapacity.

Use caution when applying loadsand torque. If the bargraph is nearly filled and isred, stop applying load or torque to prevent damage to your sensor.

OPERATING YOUR GAUGEThe DF II Series gauge may be used as a handheld instrument or mounted to a Chatillon testerfor compression and tensile testing.CAUTION: The DF II Series gauge isdesigned for axial loading only. Neverapply a side load to the load shaft.TEST STAND OPERATIONWhen using the DF

The Chatillon DF II Series digital force gauges are battery powered precision instruments used to mea-sure axial tensile or compressive forces. . Accessories used with low torque capacity (3-50 in-lb) will receive 1/4 and 3/8 Hex Drive. Larger capacities receive 3/8 and 1/2 Drives. Carrying Case SPK-DF-118
