pressed, the next prompt is “Segment two?<”, Again, pressing a ‘Y’ will display “c1 = xxxxxx” so the coefficients
can be entered. After the coefficients are entered or an [N] [ENTER] or [Enter] is pressed, the next prompt is
“Input Tempcos?<“. Pressing a [Y][ENTER] will display the following prompts:
“tslp 0.237599”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value.
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“Ref. R: 1480”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value.
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“Caltemp: 68”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value.
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“toff: 357.0000”, “Change it? <“. Pressing a [Y][ENTER] will allow the user to input a new value, a
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“tcslp: 0.1713999”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value, a
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“tcslp0: 0.0000000”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value, a
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“tcslp2: 0.00000”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value, a
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“Max. Flow = 150.00000”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value,
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“Min. Flow = 1.5000000”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value.
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is,
“dens. = 0.074914”, “Change it? <”. Pressing a [Y][ENTER] will allow the user to input a new value.
Pressing [N] [ENTER] or [Enter] will go to the next prompt which is “Input Mode?<”.
Note: Pressing [Q] [ENTER] at any time will exit this menu item and display "Input Mode?<".
COMMAND:
L. Calibrate Outputs
Summary:
Permits user to calibrate the outputs - 4 mA level, 20 mA level and heater current. A passcode must be entered.
The instrument is calibrated at the factory. This command does not need to be done unless the instrument needs a
re-calibration.
Description:
In order for the user to calibrate the output currents, a digital-to-analog converter (DAC) is set to the correct values
so that on power-up, all the currents are reset properly each time. This is accomplished by monitoring the output
currents while adjusting input to the DAC until the correct output values are reached. Both course and fine
adjustment controls are available for calibration.
