Installing the battery

The manufacturer includes a battery which must first be installed. Remove the battery cover (don't lose it!) and install the supplied battery with its positive side facing up. The manufacturer's battery may not have the full 3.5 years life expectancy. This might be because no one knows how long the batteries have been in storage. Mitutoyo is careful to point this out.

After installing the battery you will have to set the origin point on the calipers. If you don't, you're likely to see the "E" error display. Simply close the jaws and hold down the "origin" button for more than one second. The display will show 0.00 and you're ready to go.

The battery should be removed if the calipers will be in storage for more than 3 months. Replacement batteries and spare parts are available (see parts list on page 72).

Want to skip the batteries? Consider the solar-powered calipers shown on page 127.

Comparison measurement and absolute measurement

When the power is turned on, the digital calipers work just like normal dial calipers. When the jaws are closed, the reading is zero. Open the jaws and the display will give you the reading in .0005" graduations. Remember that the accuracy is only .001" so the display is somewhat misleading. Digital calipers are no more accurate than standard dial calipers.

You can set the zero at any point on the calipers in order to take comparison measurement. Open the jaws to the size you want, then press the yellow ABS button for less than a second. You'll see the letters INC displayed to tell you it's IN Comparison mode. (Get it?) To turn off the INC, you'll have to press the button for more than 2 seconds.

What's likely to go wrong?

An arbitrary value, or the letter "E" will appear in the display if the calipers have not had the origin set. See instructions above.

"ErrC" is displayed and the display is flickering when the scale surface is contaminated. That means it's dirty or wet with water. Clean the scale, dry it and apply a small amount of thin oil (low viscosity) in order to repel any future water contamination.

"E" at the end of the reading, such as 2.501E, means you've moved the slider too quickly. However, the reading is still correct. (So why do they tell you this?) Slow down a little, next time. It can't hurt.

"E" if caliper is stationary. Same as ErrC.

One more thing: if the faces are bent or worn but the electronics are still functioning, then they can be repaired. However, if the electronics refuse to do anything... add them to your local land fill. Of course, there's a one-year warranty. Keep your sales receipt handy just in case they meet a premature demise.
