HLCHI? QUERY
Reads the Hi-Lo Comparator high value from RAM for range.
Syntax:
Response:
"1.0000" for 1Ω in the 2Ω range and 100.00 for 100mΩ in the 200mΩ range.
This command reads the value from RAM memory only. If you have used the HLCHI
command to write a HLC value it will be different than the value stored in non-volatile
memory if the SAVSETUP command has not been sent.
Power-on default = Depends on range.
HLCLO COMMAND
Sends the Hi-Lo Comparator Low Limit for current range.
Syntax:
Where value = 1.0000 for 1Ω in the 1Ω range, 100.00 for 100mΩ in the 100mΩ range,
1.000 for 1k in the 1kΩ range.
This command writes the value to RAM memory only. To store these values in non-
volatile memory follow with SAVSETUP. Send RANGE command before sending this
command.
Power-on default = Depends on range.
HLCLO? QUERY
Reads the Hi-Lo Comparator low value from RAM for range.
Syntax:
Response:
"1.0000" for 1Ω in the 1Ω range and 100.00m for 100mΩ in the 100mΩ range, 1.0000k
for 1kΩ in the 1kΩ range. This command reads the value from RAM memory only. If you
have used the HLCLO command to write a HLC value it will be different than the value
stored in non-volatile memory if the SAVSETUP command has not been sent.
Send RANGE command before sending this command.
Power-on default = Depends on range.
