Function Set measure inputs settings
Command WRMETIN_<INPUT>,<REGISTER>,<VALUE>[CR][LF]
Description Set measure inputs settings.
To read exact values of input ranges it is necessary to use RDMETRANGES_ command.
Parameter(s) Default input and ranges:
<INPUT> = 0

14VDC input,
<INPUT> = 1

24mADC input,
<INPUT> = 2

10VAC input,
<INPUT> = 3

200mAAC input,
<INPUT> = 4

6AAC input,
<INPUT> = 5

16mAAC input,
<INPUT> = 6

VREF input (only for internal measurements),
<INPUT> = 7

GND input (only for internal measurements),
<REGISTER> = 0

MET_IN_MODE (set mode of ADC input):
<VALUE> = 0

ADC OFF,
<VALUE> = 1

ADC ON with auto range,
<VALUE> = 0

ADC ON with manual range,
<REGISTER> = 1

MET_IN_RANGE (set measuring range):
<VALUE> = 0

<INPUT> / 1 (e.g. 14VDC for 14VDC input),
<VALUE> = 1

<INPUT> / 2 (e.g. 7VDC for 14VDC input),
<VALUE> = 2

<INPUT> / 4 (e.g. 3.5VDC for 14VDC input),
<VALUE> = 3

<INPUT> / 8 (e.g. 1.75VDC for 14VDC input),
<VALUE> = 4

<INPUT> / 16 (e.g. 0.875VDC for 14VDC input),
<VALUE> = 5

<INPUT> / 32 (e.g. 0.4375VDC for 14VDC input),
<VALUE> = 6

<INPUT> / 64 (e.g. 0.21875VDC for 14VDC input),
<VALUE> = 7

<INPUT> / 128 (e.g. 0.10938VDC for 14VDC input),
<REGISTER> = 2

MET_IN_RESERVED
– not used,
<REGISTER> = 3

MET_IN_AVERAGE (set number of signal periods of C300 current
output from which is made average):
<VALUE>

natural number in range from 1 to 2^16,
<REGISTER> = 4

MET_IN_PROGRESS (should not to be set),
<REGISTER> = 5

MET_IN_RMS (should not to be set),
<REGISTER> = 6

MET_IN_PHASE (should not to be set),
