5. Ensure jumpers J1 to J7 are correctly positioned according to the table on the screen.
6. Connect a precision voltage source between SK1 Pin 4 (positive) and Pin 22
(negative), and ground the unused channels by connecting SK1 Pin 5 to Pin 23, Pin 6
to Pin 24, Pin 7 to Pin 25,..... Pin 19 to Pin 37.
7. Set the voltage source to +0.97mV and adjust RV2 until data reading is 2048-2049.
8. Set the voltage source to +3.999 and adjust RV1 until data reading is 2046-2047.
9. Repeat 7 and 8 if necessary.
6.7.2 Bipolar Calibration ±2 volts
1. Run the PC27E Pascal demonstration program.
2. From the main menu, press 2 to select Software Controlled sampling on one channel
only.
3. Enter 3 for Bipolar input (
± 2 volts)
and confirm.
4. Enter 1 for the channel number. (Note in the Pascal demo program, the channels are
numbered 1 to 16)
5. Ensure the jumpers J1 to J7 are positioned according to the table on the screen.
6. Connect a precision voltage source between SK1 Pin 4 (positive) and Pin 22
(negative), and ground the unused channels by connecting SK1 Pin 5 to Pin 23, Pin 6
to Pin 24, Pin 7 to Pin 25,..... Pin 19 to Pin 37.
7. Set the voltage source to -1.988 and adjust RV2 the data reading on the screen is
2048/2049.
8. Set the voltage source to +1.998 and adjust RV1 until the data reading on the screen
is 2046/2047.
9. Repeat 7 and 8 if necessary.
6.7.3 Bipolar Calibration ±4 volts
1. Run the PC27E Pascal demonstration program.
2. Select Software Controlled sampling on one channel only.
3. Enter 2 for Bipolar input (+ 4V) and confirm.
4. Enter 1 for the channel number. (Note in the Pascal demo program, the channels are
numbered 1 to 16)
5. Ensure the jumpers J1 to J7 are positioned according to the table on the screen.
6. Connect a precision voltage source between SK1 Pin 4 (positive) and Pin 22
(negative), and ground the unused channels by connecting SK1 Pin 5 to Pin 23, Pin 6
to Pin 24, Pin 7 to Pin 25,..... Pin 19 to Pin 37.
