To operate the bar code scanner, hold the wand at a slight angle (10 to 30 degrees) from vertical. Place the wand on the page either to the right or left of the code to be scanned and move the wand at a steady speed across the code to the other side. Do not stop until the bar code is completely passed over. The red light at the tip of the bar code reader will blink twice when scanning the ENTER code and will blink once for all other codes when the codes have been scanned correctly. You must l

Skein Holder (45°/0° instruments only) This is a device for measuring yarn skeins. Wind the yarn around the skein holder in multiple taut layers until it is effectively opaque and is as flat as possible. Secure it in place with the detachable arms on the sides of the skein holder. Place the skein holder at the sample port and back it with the sample clamp or a white backing tile to provide a consistent background and pressure. Make several measurements of the skein, rotating the holder 90° b

Archiving Setups All ninety-nine setups can be stored in non-volatile memory by choosing “Archive Setups” from the ColorFlex menu. When this procedure is performed, all setups will then be stored in non-volatile memory and will be safeguarded from loss due to memory failure. It is recommended that you store your setups in non-volatile memory on a regular basis. This will protect your setups should you experience an unforeseen memory loss. If you create additional setups or change existing setup

Specifications For best performance, your instrument should be placed where there is ample work space with medium or subdued illumination and no drafts. For optimum results, a clean, air-conditioned area is recommended with a relative noncondensing humidity of 5-85% and relatively constant temperature not exceeding 110°F (43°C). For specification performance, the recommended temperature range is 70- 82°F (21°-28°C). The instrument should be connected to a stable, instrument-grade power line.
