* 1. #600 ~ #603: alarm enable, from which the user can determine the type of alarm required to enable.
#600 set the alarm type 1, #601 set the alarm type 2, and so on. MTC-04-NT offers 14 alarm types, four
of which can be selected simultaneously (see 5.3.1 alarm type). For different channels, the alarm values
of 1 ~ 4 alarm determined by #600 ~ #603 are set by #606 ~ #609, #610 ~ #613, #614 ~ #617, and #618
~ #621 respectively.
* 2. #604: set the dead zone for each channel's alarm mode. In order to avoid repeated occurrence of
alarm state and non-alarm state when the measured value fluctuates near the alarm setting value, an
alarm dead zone can be set. Setting range: 0 ~ 999; Default value: 10; Unit: 0.1

. See 5.3.2 alarm
dead zone.
* 3. #605: number of alarm delay. Set the range from 0 to 255. If the measured value in the alarm range is
still within the alarm range after the set number of delayed alarm, the alarm will be given. See 5.3.3 alarm
delay.
* 4. #606 ~ #609, #610 ~ #613, #614 ~ #617, #618 ~ #621:1 ~ 4 alarm settings in channel 1 ~ 4. For
different channels, the same alarm need to set different alarm value. User enabled via #600 ~ #603

* 1. #700: when the user save the parameter, and this position is 1, the module save the parameter set by
the current user. Operating instructions are as follows:
1) when #700 is set to 1, start the data backup. At this point, you need to wait for a few seconds before
the power is cut off, otherwise the parameter may be saved incorrectly. After MTC save the parameters,
#700 will automatically clear.
