page 108 008-0608-00 Each High-Level Input channel is configured and calibrated via its channel menu. Detailed instructions on operating the instrument in the SETUP Menu mode can be found in “SETUP Menu mode” on page 23. A diagram of all menus is located in “Setup Menu Reference” on page 157. 12.6.1 OPERATION Sub-Menu This menu controls the operation of this channel when the instrument is in the RUN mode. AUTO-ZERO Menu Item This enables or disables the channel’s automatic zeroing function. The auto-zero function can remove the effect of slight temperature shifts in the transducer’s output. The two options for this menu item are “ON” and “OFF”. When enabled, the channel will reset its tracking value to zero when the tracking value has never been more positive than +10 or more negative than -10 display counts for any 10 second period. For example, assume that the DISPLAY.DECPT menu item is set to 000.00 (two decimal points). If the tracking value never leaves the range of -000.10 to +000.10 for any 10 second period, then tracking value will reset to 000.00 automatically. NOTICE To compensate for the transducer’s initial warm-up shift, the auto-zero function operates every 2 seconds during the first 60 seconds of RUN mode operation. FREQ. RESPONSE Menu Item This sets the frequency response, step response, and resolution of the channel according to the table below. The tracking value, peak/valley detector values and analog output on this channel are all affected. The default value of 016. HERTZ is suitable for most applications. Frequency Response Step Response (ms) (typical) Resolution (counts) (not including min. 10% overrange/underrange capability) 5V & 10V Inputs 1V & 4-20mA Inputs 002. HERTZ/FAST 40 ±50000 ±50000 002. HERTZ 440 ±50000 ±50000 008. HERTZ 110 ±25000 ±25000 016. HERTZ 55 ±25000 ±20000 032. HERTZ 28 ±20000 ±10000 050. HERTZ 16 ±15000 ±10000 100. HERTZ 8 ±10000 ±5000 250. HERTZ 3 ±10000 ±5000 500. HERTZ 2 ±4000 ±2500 800. HERTZ 2 ±2500 ±2500 High-Level Input Channel POWER-ON SOURCE Menu Item This menu selects which value is displayed by the channel when first entering the RUN mode. The choices are: •“TRACK” means the live tracking value of the channel. SC Series Instruction Manual page 109 • • • “VALLEY” means the lowest value of the channel. • “TRACK / PEAK” means the live tracking value and the highest value of the channel. (Only available on Model SC3004). • “TRACK / VALLEY” means the live tracking value and the lowest value of the channel. (Only available on Model SC3004). • “PEAK / VALLEY” means the highest and lowest values of the channel. (Only available on Model SC3004). page 110 008-0608-00 DISPLAY SETUP This menu controls how data values are displayed by the channel and transmitted Sub-Menu via serial communications. DISPLAY. DIGITS Menu Item Selects the number of digits displayed by the channel. The choices are: • “5 DIGIT-BIPOLAR” displays both positive and negative numbers with five full digits (±99999). • “6 DIGIT-UNIPLOAR” displays positive numbers with six full digits (999999) and negative numbers with five full digits (-99999). • “7 DIGIT UNIPOLAR” displays positive number with seven full digits (9999999) and negative numbers with six digits (-999999). DISPLAY. DECPT Menu Item Selects the decimal point location on the channel’s display and serial communications output. Use the [UP] and [DOWN] buttons to move the decimal point to the right and left. This menu item may be automatically updated by a transducer’s Signature Module. DISPLAY. COUNT-BY Menu Item Determines by what value the display increments or decrements. This will make the display less sensitive to a noisy signal. The choices are: • “00001” • “00002” • “00005” • “00010” • “00020” • “00050” • “00100” • “00200” DISPLAY. UNITS Menu Item Specifies the four character label that is displayed to the right of the channel’s values. NOTICE This menu item doesn’t change the mathematical scaling of the channel’s values; that can be changed by altering the “CALIBRATION DATA -> FULL SCALE VALUE” menu item and then performing a re-calibration. This menu item doesn’t change the mathematical scaling of the channel’s values; that can be changed by altering the “CALIBRATION DATA -> FULL SCALE VALUE” menu item and then performing a re-calibration. When a character position is flashing press the [UP] or [DOWN] button to change the character. Press [ENTER] to advance to the next character. DISPLAY. AVERAGE Menu Item Controls the speed with which the channel’s display values will update. Display averaging does not affect the channel’s analog output or its peak/valley detection, which will proceed at the speed selected by the ”OPERATION -> FREQ. RESPONSE” menu item. The choices are: • “ON” means that the display will update four times each second. The channel’s values will be averaged for 1/4 second, then displayed. • “OFF” means that the channel’s display will update as quickly as possible. High-Level Input Channel SC Series Instruction M...
