2.6SENSOR CURVE DEFINITION

To display accurate temperature, select a response curve that matches the installed sensor. There are seven standard curves stored within the Model CYD201/CYD208 numbered 0 through 6 (see Appendix A). Different curves may be assigned to each channel of the Model CYD208. Find the unit factory curve configuration inside the front cover of this manual. Curve 6 (CY-7 Curve 10) is the standard curve configuration unless specified differently upon order.

To determine current curve selection, press and hold UNITS and turn on (1) the rear panel SET switch (DIP switch 3). Release UNITS key. The CYD201 displays the curve number in the display window. The Model CYD208 displays the curve number in the display window and the channel number in the channel window. To display curves for other channel numbers in the Model CYD208, press CHANNEL to scroll through the eight channels.

To change the curve, press UNITS. The instrument scrolls through curves 0 through 6. In the Model CYD208, press CHANNEL to select other channels, then press UNITS to scroll through the curves.

After the new curve selection, turn the SET switch on the rear panel off (0). The unit returns to normal operation.

2.7RACK MOUNTING

The Models CYD201 and CYD208 can install in a standard “size” 1/4 panel EIA rack space. If you ordered a CYD208-DIN rack mounting adapter, follow the installation instructions below. See Figure 2-3.

1.Remove front feet on bottom of unit and attach lower rack piece by threading two of the four screws provided into the front feet holes.

2.Locate the two mounting hole access covers on the top of the unit. Attach the other rack with the remaining screws.
