T_MODE, T_MODE? – Trigger Input Function Selection
Functions
The T_MODE parameter assigns the floating trigger input with
optocoupler (at the analog interface) to a selected device
function.
Syntax
T_MODE

chapter 5.7.

Comment
The status of the T_MODE function is not saved as a device
setting with the “SAVE” command.
TSET, TSET? Dwell Time Specific to Memory Location for the
SEQUENCE Function
Functions
The TSET parameter setting defines memory location-specific
dwell time for a voltage-current value pair to be recalled. If no
specific value or a value of 00.00 [s] is assigned to TSET, TDEF is
used as a default value for execution of the sequence function.

Comment
Dwell times of greater than 99.99 seconds per setting can be
achieved if total dwell time is distributed to several consecutive
sequence registers with identical current and voltage settings.
If the selected dwell time for a specific sequence register needs to
be read out, the respective register must first be queried from
memory with the RCL function.
The selected TSET value is also saved to the setup register as a
device setting with the SAVE command.
Action
Description
OFF
Trigger input function deactivated
OUT
Trigger input acts upon the OUTPUT: output On/Off
RCL
RECALL: memory recall (single step)
SEQ
SEQUENCE: sequential memory recall
(SEQUENCE GO)
a)
a. If the SEQUENCE function has not first been initialized, an active trigger signal
results in error message “Err 27”, which is displayed for approximately 1
second, and bit 5 (SEQE) is set in event register B (ERB). “RCL” or “SEQ”
settings can only be executed if the SEQUENCE function has been fully
initialized (see page 71).
LLO
LOCAL LOCKED: control panel disabling
MIN
MINMAX: Min-Max memory for measured values
Default setting after RESET (*RST): unchanged
