*For reasons unknown to us, Tesa has assigned two numbers to the same item. It is possible that in an earlier incarnation, one item was switchable metric/inch while the other was strictly metric. There is now no option. This Digico 205 is only sold in the metric/inch version. For USB connection cables, select the OPTO-USB style. This gage can also be used with a wireless transmitter. Both are shown on page 227.
Some easy usage tips
Although it's described in detail in the instruction book, the button on the lower right is pressed a few seconds until you see the word "PRESET" flashing near the top of the display. When you let go, the display will read 0.0000 (zero). The indicator shuts off after 2 hours but you may want to do this sooner. Press the on/off button on the lower left for a few seconds. When you let go, the display turns off. |
