Command Reference
TDV
irange: Ranging type for current output. Integer expression. The output range
will be set to the minimum range that covers current value. For the
limited auto ranging, the instrument never uses the range less than the
specified range. See Table 4-5 on page 4-22.
current: Output current (in A). Numeric expression. See Table 4-6 on page 4-23,
Table 4-8 on page 4-25, or Table 4-11 on page 4-27 for each
measurement resource type.
Vcomp: Voltage compliance value (in V). Numeric expression. See Table 4-6 on
page 4-23, Table 4-8 on page 4-25, or Table 4-11 on page 4-27 for each
measurement resource type. If you do not specify this parameter,
Vcomp is set to the previous setting.
polarity: Polarity of voltage compliance. Numeric expression.
0: Auto mode (default setting). The compliance polarity is
automatically set to the same polarity as current, regardless of the
specified Vcomp. If current=0 A, the polarity is set to positive.
1: Manual mode. Uses the polarity of Vcomp you specified.
vrange: Voltage compliance ranging type. Integer expression. The compliance
range will be set to the minimum range that covers Vcomp value. For
the limited auto ranging, the instrument never uses the range less than
the specified range. See Table 4-4 on page 4-21.
Remarks To read the time data with the best resolution (100 μs), the timer must be cleared
every 100 sec or less for the FMT1, 2, or 5 data output format, or
every 1000 sec or less for the FMT 11, 12, 15, 21, 22, or 25 data output format.

ENTER @B1500 USING "#,3X,13D,X";Time
TDV
Forces voltage and returns the time data from timer reset to the start of output. This
command is not effective for the 4 byte binary data output format (FMT3 and
FMT4).
Execution
Conditions
The CN/CNX command has been executed for the specified channel.
If the output voltage is greater than the allowable voltage for the interlock open
condition, the interlock circuit must be shorted.
