Event(ineffective)
For TRIGGER or REPEAT, one event must be set for the WR TRIG action during event/action
function setting. For a detailed description of the event/action function, refer to 9.1, “Setting
Event/Action Functions” (page 9-1).
Data write interval (WRITE SAMPLE)
The data write interval at which data is saved can be selected from the following.
INTVL: Same as measurement interval. Every set of measured/computed data is saved.
1 min, 2 min, 5 min, 10 min: Saved at the specified interval.
LOGIC: One piece of data per channel is saved each time the event specified by DATA WR
(event/action function) occurs. For a detailed description of the event/action function,
refer to 9.1, “Setting Event/Action Functions” (page 9-1).
Data length (WRITE LENGTH)
Used to set the number of pieces of data per channel. Select one of the following options.
10, 20, 30, 40, 50, 100, 200, 300,. 400, 500, 1k, 2k, 3k, 4k, 5k, 10k, 20k, 30k, 40k, 50k
Some options cannot be selected depending on the number of channels to be saved or the number
of computation channels.
Pre-trigger (PRE TRIGGER)
If REPEAT or TRIGGER has been selected as WRITE MODE, data which occurs before the
trigger (event) is activated can be saved within the specified data length. Set the trigger timing in
units of percentage (%) of the specified data length in steps of 10%.

File name
If DIRECT or TRIGGER has been selected as WRITE MODE, the file name must consist of up
to 8 characters. If REPEAT has been selected as WRITE MODE, the file name must be of up to 5
characters in length. The lower 3 digits of the file name indicate the serial number (001 to 208).
