Adjusting Low Resistance Output:
1. Connect Digital Multimeter ohm input (4-wire) to ASC-400 Ohms source
terminals.
2. Set up Digital Multimeter for True ohm mode, 1 mA ( 3 mA max.) excitation
current.
3. Type "7" in the Calibration menu.
Prompt = "First calibration point. Enter ohms output:"
4. Enter multimeter read value when stable (example: 5.000) and press "enter".
Prompt = "Second calibration point. Enter ohms output:"
5. Enter multimeter read value when stable (example: 400.000) and press "enter".
ASC-400 now returns to the Calibration menu.
5.8
Adjusting High Resistance Output:
1. Connect Digital Multimeter ohm input (4-wire) to ASC-400 Ohms source
terminals.
2. Set up Digital Multimeter for True ohm mode, 0.1 mA (0.3 mA max.) excitation
current.
3. Type "8" in the Calibration menu.
Prompt = "First calibration point. Enter ohms output:"
4. Enter multimeter read value when stable (example: 400.00) and press "enter".
Prompt = "Second calibration point. Enter ohms output:"
5. Enter multimeter read value when stable (example: 4000.00) and press "enter".
ASC-400 now returns to the Calibration menu.
5.9
Adjusting Resistance input:
1. Connect Calibrator to ASC-400 Ohms measure terminals using 4-wire
connection.
2. Set up Calibrator for 4-wire connection.
3. Type "9" in the Calibration menu.
Prompt = "Input 15 ohm to ASC400 - Press <enter> when stable"
4. Apply 15.00 ohm to the input and press "enter" when stable.
Prompt = "Input 400 ohm to ASC400 - Press <enter> when stable"
5. Apply 400.00 ohm to the input and press "enter" when stable.
Prompt = "Input 4000 ohm to ASC400 - Press <enter> when stable"
6. Apply 4000.0 ohm to the input and press "enter" when stable. ASC-400 now
returns to the Calibration menu.
