Common questions about manuals, registration, and support for this brand.
For models like the 733.1 series, remove the battery cover using a coin or screwdriver. Install two CR2032 lithium batteries: the first with the negative side down and the second with the positive side down. Replace the cover and perform the startup calibration sequence.
After replacing batteries, the display will show 'CAL'. Move the thimble very slowly in one direction (approx. 0.25 inch over 2-3 seconds) until the display shows a measurement reading. This initializes the accuracy tuning function.
Press and release the ZERO/ABS button. A dashed line may appear while the tool zeros out. Do not move the spindle during this brief sequence. For absolute mode, press and hold the button for about two seconds.
Error codes on electronic measuring tools often indicate a dirty scale or low battery. Clean the scale with a lint-free cloth and isopropyl alcohol, and check or replace the battery if the issue persists.
