Q.Can we correct set counts in Auger controller by giving weight feed back from weighing scale?

Q. How we can check weight variation in SCL Weigher?

Ans: we added check mode for weight [LC count] variation. Press “F” key and then “Prog” key by pressing “Ent” key go “vibration check mode” LCD shows Minimum and Maximum counts of Load Cell [To reset counts press “F” key.].

Q. How we calibrate Pressure in PC903 ventilator?

Ans:  At power on press “Keypad Lock” key up to life resets to 0000 then controller enters into Test Mode. Press “Enter” key to go into PRESSURE CALIBRATION Mode here user have to adjust pressure LED to 00 by rear zero trim-pot on pressure PCB (Take care that no pressure applied to controller). Now apply some pressure (by PEEP value) and user can compare pressure LED bar & manometer. To exit from test mode press “Enter” key.

Q. Which steps follow to Serial out Record data from Micro Temperature Detector?

Ans:

i) Open Hyper Terminal and Enter Port Settings:
Bits per Second: 2400
Data bits: 8
Parity: None
Stop Bit: 1
Flow Control: None
ii) For Capturing Data :
Go to Transfer  à Capture Text
(Enter the Path & name of the TXT file in which records to be captured and
Click on “Start“. Use Brows option to set the path.)
iii) Press “FUN” key of Micro Temp Indicator.
Enter “YES” for “WANT TO SERIAL OUT ”.
iv). after all records are SERIAL OUT then click on Transfer menu à capture textà
click on Stop to end capturing.
v) Open a new Excel sheet
i] Go to File Menu ==> Click “Open” , Select “Files of Type” as Text files &           .    Select the required Text file & click ‘Open’ button

Q. Explain Steps for 3 point calibration in Micro Temperature Indicator?

Ans:  User can enter in calibration mode by pressing ENT key at power on.

Following is procedure for indicator sensor.
On site only step 3,4,5 are valid.

2. Short analog input & make output of first stage OPAM to 00  mV  [at pin 6 of U18] OR adjust ADC count on LCD to 00 by zero trim pot (P1)

3. Now apply full range analog input [e.g. 20.20mV for R-Type] & adjust the display [1700C] for that vary span trim pot  (P4)

4. Now apply in between analog input [e.g. 13.22mV for R-Type] & adjust the display [1200C] for which vary offset trim pot. ( P3)

5. Repeat 3 & 4 to get exact full scale & in between value.
