Setting range of OFST command. (when probe ratio is 1:1)
Trace Vertical sensitivity
2mV/div ∼ 50mV/div
100mV/div ∼ 500mV/div
C1,C2,C3,C4
1V/div ∼ 10V/div
M1 (+, -, X)
M1 (FFT)
Any value outside the above range is rounded to the maximum or minimum
permissible value, whichever is nearest. In addition, some value may be rounded
to a permissible smaller value.
When the probe ratio is 10:1, 20:1, 100:1, 200:1, 1000:1or 2000:1, the above
range is multiplied by 10, 100, 1000 or 2000.
When the probe ratio is set to "AUTO", the above range is multiplied by 1, 10,
or 100, depending on the detected probe ratio.

OFST
Command/Query
The OFST command sets the vertical position (offset)
of the specified input channel.
The setting range depends on the vertical sensitivity.
The OFST? query returns the defined vertical position
(offset).
Both command and query are always available regardless
if the specified channel's trace is on or off.
Probe ratio is considered in the vertical position
(offset) value to set or query.
<trace>:OFST <offset>
<trace>: = {C1, C2, C3, C4, M1} (WJ354/334/324/314)
: = {C1, C2, M1} (WJ352/332/322/312)
<offset>:= Offset voltage. The <DECIMAL NUMERIC
PROGRAM DATA> format is basically used in <offset>, and
the suffix is also valid. For the setting range and
rounding rule, see "Remarks".
<trace>:OFST?

The current offset is identified in <offset> in <NR3
