OPERATING INSTRUCTIONS
1) Place V-Height under object to be measured.
2) With the V-Height placed flat on the ground plane, set the contact probe at its lowest position and depress BASE once. The display will register the starting height of the probe in one of the selected units of measurement.
INCH-DECIMAL: BASE = .750
INCH-FRACTION: BASE = 3/4
MILLIMETER: BASE = 19.0
3) Free the contact probe from its base position by gently pulling up on the contact probe with one hand, ensuring the body of the V-Height remains flat on the ground plane with the other.
4) Allow the contact probe to rise until the tip touches the point of interest. The reading displayed is the vertical measurement from the ground plane to the measured point.
5) Although additional measurements may be taken without repeating step 2, it is advised that steps 1 through 4 are repeated for all measurements to ensure that the device is starting from ground level.
Note: Pressing BASE will set the height to its lowest nominal value of .75 inches (or equivalent). Do not press base if the contact probe is not at its lowest (horizontal) position. Doing so will result in inaccurate measurements.
CONTACT PROBE
The hard-coated contact probe uses the rounded tip at its end as the contact surface.
Use only this rounded surface to contact measured objects. The round tip is available at all points in the measurement range and will be the first (and only) surface to touch the measured object.
USING STILTS
V-Height devices are provided with four stilts. These are used in instances where the measured object is slightly raised above ground. A prime example is an automobile on four scales. With each tire on a 3-inch-thick scale, measurements from the chassis to ground level are offset by 3 inches. By setting V-Height flat on a scale surface and dropping the stilts to the ground, the measurement output will be just as if the car was on the ground. This allows the user to simultaneously weigh each wheel of the car and measure the frame stance. Stilts can translate the measurement ground plane up to 6 inches above the original ground plane.
CHARGING
After several hours of use, you will notice an amber-lit LED beside the label, “LOW BATTERY”, at the upper-right corner of the touchpad. This signifies that the device battery has one-half hour of working charge before powering down. To charge the battery, plug the supplied transformer first into the back side of the device, then plug the other end into a 115 V power receptacle. While charging, the green-colored “CHARGE” message will be lit. When fully charged, the “CHARGE” light will go turn off and nothing will be displayed in the upper right corner of the display.
This device is equipped with an internal rechargeable lithium-ion battery. The battery will last for several hundred charges and, if cared for properly, will last for the duration of the product life. The battery is not removable. In the event of a problem with the charge life or battery leakage, contact V-Height tech support 704-500-7155.
Do not leave V-Height plugged into the charger for extended periods of time (over 12 hours). It is possible to overcharge the battery and shorten battery life.
STORAGE
V-Height comes equipped with a storage case. It is advisable that when not in use or charging, the device and its battery charger are put in the case and the case is closed. This will keep the device safe from projectiles and/or liquid spills. Do not store V-Height in temperatures below - 32º F or above 120º F, or in damp or humid (over 90% humidity) areas.
APPLICATION EXAMPLE: RACE CAR FRAME HEIGHT MEASUREMENT
It is common in auto racing to attain measurements under the chassis, and in the case of cars like those competing in NASCAR events, at each corner of the chassis. Frame rail corner heights are important because they are controlled by rules and also affect the handling of the car. Using under-tire scales to read corner weights, the chassis is raised or lowered at each corner to strike the correct balance of both height and weight. Most commonly, the height measurements are made with a measuring tape. Using this method, the user may experience awkward body positioning, eye strain from reading tape marks in dimly-lit areas and the prospect of circling all four corners of the car several times until the proper height is reached on all 4 corners of the chassis. In addition to this, time is also wasted by factoring fractional tape measure marks to the least common fractional denominator.
Measurements made using the V-Height eliminate error caused by tape mark interpretation and factoring. In addition, measurements are more repeatable and can be made more comfortably.
Race car chassis setup is merely one use for this device. There are many other uses for this concept outside of the realm of the automobile. The use of this apparatus is useful on any application requiring the normal distance between a plane and a point.
