Setting a High End set point on the 4-20mA outputs through the transmitter front panel keys does not always function as designed. The transmitter will either reboot or lock up when the transmitter Line 4 display of the calculated High End set point (inclusive of spaces and units) is greater than 20 characters. This problem will also occur if using the Flow Cutoff Range High End setting in the CUSTOMIZE menu. When the transmitter reboots (or locks up and followed by reboot) the transmitter Data History will be erased. The problem appears to be isolated to Firmware Release 04.02.25 and 04.02.26.
