Question: Which click wrenches have to be turned down to the bottom of the scale for storage?

Answer: Every click wrench other than the "C" series must be returned to the bottom of the scale after use. Springs in micrometer style wrenches will "take a set" after time and this will affect the calibration of the wrench. The "C" series does not use a coil spring and therefore can be stored at any value.

 

Question: Which torque wrenches work in both directions?

Answer: ALL torque wrenches other than the "C" series work in both directions. The "C" series works only in the clockwise direction, except the C4D600F series’ ratchet can be flipped over to allow for counter-clockwise applications. The accuracy of the D and M series is the same clockwise and counter-clockwise, but other wrenches may have different specifications based on direction.

 

Question: What does the "M" in a D2F150HM stand for?

Answer: Memory model Retains the highest torque reading for easy reference. For Quality Control testing, a memorymodel displays the maximum reading obtained. This is excellent for verifying production torque applications.

 

Question: How do I use the "M" (Memory model) option properly?

Answer: To use the Memory model in the clockwise direction, rotate knurled knob counter clockwise on top of crystal until the memory pointer contacts main pointer. Next turn the dial bezel counter clockwise until the memory pointer is on zero. Place the torque wrench on the fastener and pull on the wrench handle until the desired torque is reached. When the pressure is released the main pointer will return to zero and the memory pointer will remain at the peak torque reached. For counter clockwise direction use, reverse above procedure. The memory model feature can be used to record peak torque when the dial may not be visible. Be careful not to overtorque the fastener or torque wrench.

 

Question: What does the "L" in a D2F150HL stand for?

Answer: Indicator Light Model Indicates when a preset torque level is achieved. Set the dial to the required torque, and the light will go on when the proper torque is reached. This is particularly useful when the dial is not visible.

 

Question: How do I use the "L" (Lighted) option properly?

Answer: To use the Indicator Light Model for clockwise applications, turn the dial until the gold pointer is set at the desired torque (the red pointer for counterclockwise applications). Place the torque wrench on the fastener and pull until the light comes on. Check the bulb and battery if the light fails to light when the pointer touches the gold contact pin.

 

Question: What is the difference between a "C4D600F" and the "CP4D600F"?

Answer: The CP4D600F is a preset model meaning that the wrench comes from factory preset to a specific torque. A user with a torque tester can also adjust the torque setting.

 

Question: Where should preset models be used?

Answer: Preset torque wrenches such as the CP click wrench series and the MSP fully releasing driver type wrench are best suited to applications where a specific torque is applied over and over. They provide the user with the ability to set the torque and be assured that the setting will not accidentally be changed during production.

 

Question: Is a "M" micrometer style wrench calibrated in the same way as other micrometer style wrenches?

Answer: NO! The "M" series requires special tools available to perform calibration. DO NOT DISASSEMBLE a "M" wrench as you would other micrometer style wrenches! The mechanism in the "M" does not rely on shims, spacers or blocks to perform calibration. Instead, all calibration is performed externally, quickly, and without the need to disassemble the wrench. This keeps the internal components free from outside contaminates, eliminates calibration kits, and makes "tweaking" the calibration very simple.

 

Question: How often do torque wrenches require calibration?

Answer: The more a wrench is used, the more it will require calibration. Every wrench regardless of use should be calibrated at least every six months to ensure perfect calibration. Production units may require calibration every month, week, or day! Users should be encouraged to maintain wrench calibration and, when establishing their calibration intervals, to request calibration certificates that indicate the readings after the calibration and as the wrench was received.
