One Point Calibration

Note: Be sure that a probe zero has been done prior to performing this

calibration procedure.

1) Physically measure a location on the sample to be measured using a set of

calipers or a digital micrometer. Note: It’s always best to calibrate on the

thickest location on the sample, rather than on the thinnest location, as the

percentage error is much less with respect to the PR-8V’s resolution of +/-

.001” (0.01mm).

2) Apply a drop of couplant on the transducer. Place the transducer in steady

contact on the known thickness location. Be sure that the reading is stable

and the repeatability indicator, located in the top left corner of the display, is

fully lit and stable. Press the MENU key once to activate the menu items tab.

Press the MENU key multiple times to tab right and the ESC key multiple

times to tab left until the CAL menu is highlighted and displaying the

submenu items.

3) Use the UP and DOWN arrow keys to scroll through the sub menu items

until ONE POINT is highlighted.
