    *Note: The above has given all parameters of the instrument; in case of non-full-featured instrument, parameters for functinos not available will not be specified.
       For example: 

         Note 1: the time display function of the SV screen is initiated only after the printing function is launched.
         Note 2: the fourth alarm mode "disconnection alarm" will be turned on only upon request by customers.

    Note: in the above diagram, if one group of terminals has different functions, only one of them may be available. For example, RS485 and RS232 are on the same group of terminals, so only one of them can be selected.

⑨Remarks

N/A, omissible

Remarks:

1. Please select functions based on wiring diagram upon model selection. As terminals of smaller instrument are less than those on bigger ones, only one of several functions may be selected on the same group of terminals.
2. Model F has no RS232C printing interface, and model H has no RS232 communication interface or RS232C printing interface.
3. The contact capacity of the relay of the instruments with specifications and sizes of the D or E mode is AC 125 V/0.5 A and DC 24 V/0.5A in case that there are alarms between terminal 25 and terminal 36 of these instruments, so it is the instruments with specifications and sizes of the H mode, while the relay contact capacity of other instruments is AC 220 V/2 A and DC 24 V/2 A.
4. The model must be written in detail; functions not selected shall not be omitted but marked with "X". Example 1: NHR-E100A-55-0/X/2/D1/1P(24)-A
