Table 4-8. Command and Query Reference (cont)
REMS Remote without Lockout (RS-232 only)
Enter the IEEE-488.1 remote without front panel lockout (REMS) state.
The REM annunciator is lit, and only the following three front panel
buttons are now active (with special REMS functionality):
Q triggers a single scan.
G generates a service request.
K returns the instrument to normal front panel control.
If this command is used with the IEEE-488 interface, an Execution Error
is generated.
REVIEW_CLR Clear Review Values
Clear all minimum, maximum, and last values (all channels) in the
Review array. (It is not possible to selectively clear individual entries in
the Review array.) The Review clearing operation is carried out only at
the completion of any scan in progress.
Clearing the Review array also clears all alarm status.
RTD_R0 RTD Ice Point (R0)
For the indicated channel, store the numeric data as RTD R0. Successful
execution of this command clears all Review array values (all channels.)
RTD_R0 <channel>,<R0>
<channel> = (0 .. 20)
<R0> 0 <= R0 <= 999.99
An Execution Error is generated if the R0 value supplied is not within the
indicated range, the channel specified is invalid, the channel is defined
as OFF, or measurements are active.
RTD_R0? RTD Ice-Point (R0) Query
Return RTD R0 (ice-point resistance) value for the indicated channel.
RTD_R0? <channel>
<channel> = (0 .. 20)
If the channel number is invalid, an Execution Error is generated. If a
channel is defined OFF, or if no change has been made to R0 for a
channel, the value "100.00" is returned.
