Command References
● Request to Send Real-time Data
RR command
Description Used to acquire current measured value. The data can be
consecutively acquired with a parameter following the command.
Command ・Single data acquisition : RR,1
・Consecutive data acquisition : RR,2
・Consecutive acquisition stop : RR,0
Return ・Single and consecutive data acquisition
RR, S, MDDDDDDAUFFx
S : Status→ N=Normal O=Over B=LowBatt
M : Sign “−” or “＋”
DDDDDD : measured value
A : auxiliary unit (k, m, etc.)
U : unit (V, A, etc.)
FF : measurement function (DC, AC, etc.)
x : Checksum
Example)
DC432.10mV → RR, N, +432.10mVDC7
● Request to Send Save-mode Data

A : auxiliary unit (k, m, etc.)
U : unit (V, A, etc.)
FF : measurement function (DC, AC, etc.)
x : Checksum
・When data with a specified number does NOT exist in logging-
mode memory
RLE
● Request to Send Logging-mode Data Count
RN command
Description Used to acquire the count of data in DMM logging-mode memory.
Command RN
Return RN, nnnnnx
nnnnn : logging-mode data count (00000 to 01000) (KEW1061)
nnnnn : logging-mode data count (00000 to 10000) (KEW1062)
nnnn : logging-mode data count (0000 to 1600) (KEW1052)
x : Checksum
● Request to Send Interval of Logging-mode Data
RI command
Description Used to acquire the measurement interval of data in DMM logging-
mode memory.
Command RI
Return RI, nnnnx
nnnn : interval of logging-mode data (0001 to 1800) sec
x : Checksum
