7. 4 Basic Force Gauge User s Manual Introduction BFG Power Supply Warning When alkaline batteries are fitted the AC adaptor charger must NEVER be connected to the BFG due to risk of acid leakage which could damage the instru ment The Quantrol Basic Force Gauge BFG can measure tensile and compressive forces accurately while still being easy to operate Please check the unit for any physical damage If any damage is found please notify your authorized Quantrol dealer The most commonly used features of the BFG are accessed with a single key press on the instrument displaying force peak hold Zero changing units of measure Other features can be accessed easily by pressing and holding different 2 key combinations The BFG comes with five Nickel Metal Hydride AAA rechargeable batteries For safety reasons 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 BFG To insert the batteries you must first remove the battery cover on the rear of the gauge by unscrewing the two retaining screws Fit the batteries in the battery holder Be sure to match the marked polarity Refit the battery cover and tighten the screws Connect the AC adaptor charger to the BFG charger Socket and charge the batteries for 14 16 hours Only use the adaptor charger supplied The
