With amplification the range of the probe increases making it sensitive to changes further away than usual This is only a part of what UltraCal does but it is this fact that requires that UltraCal to be used carefully UltraCal is best used for small short springs that are difficult to measure As the percentage of correction displayed on the UltraCal screen increases so does Sensitivity to other objects around the spring sensitivity to the operator s hand catching springs Temperature Drift With a normal setup the effective With a high percentage UltraCal setup measurement area of the probe is this area of sensitivity can increase to near the tip 12 inches 12 4 1 1 Other Objects During UltraCal setup objects in the area of the spring tooling sorting devices etc must be in the exact same position and location as they are when the read switch triggers the gage In normal setup the probe senses only objects within one or two inches of the tip With a high percentage UltraCal setup this area of sensitivity can increase up to 12 inches 12 4 1 2 Operator s Hand At high percentage UltraCal setups the operator s hand can be sensed as far as a foot from the tip When catching springs for testing keep your hands far from the probe tip 12 4 1 3 Temperature Drift The amplified probe signal also amplifies any temperature related errors The temperature drift of the Tiger probe is nearly non existent with a normal setup Wi
