Accumulating the Measurement Value in the Memory (Data Storage Function)
Up to 131072 measurement values of OUT1 and OUT2 (65536 values for each OUT1 and 2)
can be stored in the internal memory for every accumulation rate. The accumulated data can
be read by using the "RS-232C interface" or "LK-Navigator".
The setting contents of the function No. and the sub-function are as follows.
• The data to be accumulated is the measurement value of OUT1 or of OUT2 after data
processing such as the one in the measurement mode. ( page 3-2)
• The accumulating operation stops when the number of accumulated data exceeds the
specified number.
• The accumulation time can be calculated by "sampling rate x accumulation rate x number of data".
• The data is accumulated at the sampling rate even when the refresh rate is longer than
the sampling rate, which is set in the setting of the average number of times. In such a
case, the same measurement value continues to be accumulated until the
measurement value is updated.
• The accumulation continues without clearing the accumulated data even if [Auto-zero]
or [RESET] is performed.
• When the starting and finishing operation are repeated, the new data is accumulated
after the old data.

Starting/finishing the accumulation and clearing the data
Function No. Selection of the
accumulated data
f-d0 off Does not accumulate data.
f-d1 out1 Accumulates the data of
OUT 1
f-d2 out2 Accumulates the data of
OUT 2
f-d3 out1.2 Accumulated the data of
both OUT1 and 2
Conditions for starting
the accumulation • Start command from the RS-232 interface.
• Operation from the setup support software "LK-Navigator".
Conditions for finishing
the accumulation • Stop command from the RS-232 interface
• Operation from the setup support software "LK-Navigator".
Conditions for clearing
the accumulated data Following operations while stopping the accumulation
• When moving to the measurement mode from the setting mode or communication mode
• When initialization command is sent from the RS-232 interface
• Initializing operation from the setup support software "LK-Navigator"
• When the power is turned off
• When the program No. is changed
