1.3.2 Calibrating the Low End of the Output Range
1. Press [F1] to calibrate the low end of the output range.
2. Press [F1] or [F2] to adjust the ammeter reading UP or DOWN, until a 4 mA reading is achieved. If you press [F3],
Numer, enter a numeric value for the calibration point and press [ENT].
3. Press [F4] to STORE the setting, or press  and [F1] to ABORT the calibration.
Note: If the ammeter reading cannot be adjusted within 5.0 A of the 4 mA setting, contact the factory for assistance.
1.3.3 Calibrating the High End of the Output Range
1. Press [F2] to calibrate the high end of the output range.
2. Press [F1] or [F2] to adjust the ammeter reading UP or DOWN, until a 20 mA reading is achieved. If you press [F3],
Numer, enter a numeric value for the calibration point and press [ENT].
Note: If the ammeter reading cannot be adjusted within 5.0 A of the 20 mA setting, contact the factory for
assistance.
3. Press
[F4] to STORE the setting, or press  and [F1] to ABORT the calibration.
Note: Skip the next section if the linearity test will not be performed at this time. Proceed to Procedure Options on the
