Increase or decrease the simu- lated input until the output meter shows the desired levels and push the DOWN (zero) and UP (span) respectively for the minimum (e.g. 4mA) and maximum (e.g. 20mA) levels. The front LEDs’ colors and flashing patterns help you to easily identify the transmitter’s status and confirm the set- up actions in each step of Calibration Modes. See detailed explanation in “Calibration Flow Chart.” The calibrated input and output ranges are stored in the in- ternal memory. The module reads the DIP-switch-calibrat- ed configuration only once after the power supply is turned on. Set the switches with the power supply removed.
