« on: March 18, 2002, 10:02:51 AM »
Hi everyone i hope all is well i am just trying to pick your brains.  can you tell me if you can vary the voltage on the Dac and how much current is also there is it proportional to the voltage my units are 888. is it possible with which commands
 
thanks Karen

Technical support / input variables
« on: June 26, 2002, 01:24:38 PM »
is it possible to input two variables using the same keys
so you have the up down keys to change a number on the screen then the enter keys to input the variable then the screen changes and using the same up down key to change the number and the same enter key to key in the variable
thanks

Technical support / number display question
« on: November 05, 2002, 10:45:05 AM »

please can you tell me how i can make the screen show 1 and not 239 when i press the button other wise i have to keep pressing the button until it reaches the lower numbers



x = x - 17 ' Progressive increment after every call
IF x > 3800 THEN j=0: ENDIF
IF x > 3800 THEN x=0: ENDIF
j = 240 - X*240/3800

SETLCD 0,1,CHR$(1)  ' clear screen
SETLCD 1,1,"Select Current          "
SETLCD 2,1,"Current =" +str$(j)
SETLCD 4,1,"Press Enter"

thanks

Technical support / decimal point
« on: November 18, 2002, 09:25:07 AM »
x = x + 8 ' Progressive increment(??) after every call  
IF x > 3800 THEN  
    j = 0
    x = 0    
ELSE  
    j = 240 - X*240/3800  
ENDIF
  


SETLCD 0,1,CHR$(1)  ' clear screen
SETLCD 1,1,"-------INPUT---------"
SETLCD 2,1,"      Current"
SETLCD 3,1,"        "+str$(j)+" ma"        
SETLCD 4,1,"_____Press Enter____ "

how do i show a the number with a decimal point the variable is j  ;D

thanks

i wonder if you can help me with this problem that i have i have removed the relay thermostat that i had and replaced it with the lm35 into the adc(1) this should make reading the tempreture more accurate. Now for the problem. ?i want to show the first screen warming until the temp is reached. then i want to show the screen palting and the timer to start but i also need the temp to be consistant so cutting in at 58 and cut out at 62 how can i customise this to give me this please

thanks Karen

Technical support / Logical problem
« on: December 12, 2002, 11:31:27 AM »
' heater control function

    ' SETIO heater  or CLRIO Heater based on the
    '  value of ADC(1)/10  
 
IF ADC(1)/10 < 15 SETIO HEATER
ENDIF

IF ADC(1)/10 > 17 CLRIO HEATER
ENDIF




thanks for all the help that you have given me i would like your knowlege. i just have one more question  for you.  the above statement works great in theory but the problem is the heater works ok when it reaches 17 the heater cuts off and the value at ADC(1) rises by 10.  this means the liquid cools too much because it takes too long for the number to return to 15.  how can i compensate for the increase by ten is there any way to subtract 10 from the upper value.  so

heats to 17 heater turns off 0.5 of a second later
value rises to 27 at ADC(1) need to subtract 10
so the numer cools from 17 to 15 then repeat again

thanks karen ???
