Parameters of Commands and Responses
For information on each error, refer to "SK-1000 Series Instruction Manual"
• When the data read from a sensor amplifier is "00005":
"5" converted to binary number is "0000 0000 0000 0101".
Therefore, this data indicates that an "Overcurrent error" and a "Head error" have
simultaneously occurred at the sensor amplifier from which the data was read.
• If no error has occurred at the sensor amplifier, the data "00000" is returned.
*4
You can read data number "036" to check the judgment output status.
Convert the two digit number (ASCII characters) read from the sensor amplifiers to a binary
number and check the ON/OFF state of each bit to check the judgment output status.
When the data read from a sensor amplifier is "05":
"05" converted to binary number is "0101".
During N.O.
*5 When the data read from the sensor amplifiers is one of the following values, it is not a
comparator value but has a specific meaning.
*6 This is -999.8 when the temperature is not acquired correctly.
*7 This is 999.8 when the humidity is not acquired correctly.
*8 If a prohibited combination of functions is written, an "abnormal setting (1)" will result.
For details on each function, see the "SK-1000 Series Instruction Manual."

Readout data Details
+EE.EEE The sensor amplifier encountered an error.
+99.999 The value is +99.999 or exceeds the upper display range.
-99.999 The value is -99.998, -99.999, or exceeds the lower display range.
-99.998 The value is "-----".

Parameters of Commands and Responses
*9 The execution result for the item last requested, either the zero shift execution request or zero
shift reset execution request, is read.
*10 This item includes the results for the initial reset execution.
*11 You can read data number "56" to check the system parameter of the sensor amplifier. The
system parameter means the polarity of judgment output and alarm output, and the setting for
analog output. Convert the two digit number (ASCII characters) read from the sensor amplifiers
to a binary number and check the ON/OFF state of each bit to check the system parameter.
When the data read from a sensor amplifier is "006":
"6" converted to binary number is "0110".
Therefore, the setting of the amplifier from which the data is read is "NPN output" and
"Analog output 1 to 5 V".
*12 The external input status is where the external input is [1] when input status is ON, [0] when
status is OFF, and the 0,1,2,3 bits correlate with external input 1,2,3,4.
When the data read from a sensor amplifier is "06":
"6" converted to binary number is "0110".
