5.4 Calibration
5.4.1 Calibration (4 - 20 mA)
Channel boards are configured to accept 4 - 20 mA input signals from two-wire or three-wire remote transmitters. The
controller does not require any calibration.
During calibration of MSA's Ultima X Gas Monitors, the GasGard XL unit shows the following:
• For combustibles and toxics, if cal enable is ON, the 3.75 mA signal does not show a fault or underrange state on the
GasGard XL unit. The display may show 0 or some negative value, depending on the Dead Band Around Zero
setting.
• For oxygen, if cal enable is ON, the 21 mA signal causes the GasGard XL to go into an overrange status. As soon as
the signal drops below 20.4 mA, the user must clear this state by pressing the RESET button.
