x = 0 – Power Off functionality disabled,
x = 1 – Power Off functionality enabled
(the instrument will be switched-off
after reaching the threshold level
V
Off
),

– switch-off threshold level in [V]
(from 6.0 to 14.5),
y = 0 – Power On functionality disabled,
y = 1 – Power On functionality enabled
(the instrument will be switched-on
after reaching the threshold level
V
On
),
V
On
– switch-on threshold in [V] (from
6.5 to 15.0).

if (x = 1) and (y = 1) then (V
On
–V

#7,TL,<mask>,<nr>;
where
<mask> - mask of the returned results, see

<nr> - number of the results to read
Instrument’s response:
#7,TL,<run>,<mask>,<step>,<cnt>,<left>,<dd/
mm/yyyy>,<hh:mm:ss>,<result1>,<result2>,...
<result>;
where
<run> - measurements run flag
0 - measurements are running
1 - measurements are stopped
<mask> - mask of the returned results in
hexadecimal notation
00001 - Lpeak values in profile 1
00002 - Lmax values in profile 1
