*1: “Factory NAMUR category” refers to the four categories (C: Check function, M: Maintenance required, F: Failure, and O: Off
specification) according to NAMUR NE107*.
* NAMUR NE107 “Self-Monitoring and Diagnosis of Field Devices”
*2: When the device detects “AL02 AMP.ERR,” “AL03 FUP.ERR,” “AL10 S1.FAIL,” “AL11 S2.FAIL,” and “AL12 RJ.FAIL”, the LCD
display stays on regardless of the status in LCD mode.
*3: When the ambient temperature is higher than 60°C, AL.70 may be generated despite the indication of Energy Left shows sufficiently
remained. However, it does not affect the device operation. This is caused by the change of battery inner status with extremely
low power consumption under high temperature environment. It is recommended to set the data updating period to 15 seconds or
shorter.
*4: Applicable for dual input type with detachable antenna, Amplifier housing code 8 and 9.
*5: Applicable for single input type with integral antenna, Amplifier housing code 7.
