RATE Select Measurement Rate
Specifies the measurement rate. Changing the measurement rate also clears the
Review array, and ALARM OUTPUTS and DIGITAL I/O lines.
RATE 0 Selects the slow measurement rate.
RATE 1 Selects the fast measurement rate.
Selection of the fast measurement rate using the RATE 1 command will speed up
the measurement portion of the scan interval; however, the measurement resolution
is four digits instead of five digits. For example, a reading of +115.32 with a slow
measurement rate would be +115.3 with the fast measurement rate. An Execution
Error is generated if the argument is not 0 or 1 or if the instrument is scanning.
RATE? Measurement Rate Query
Return measurement rate for the instrument.
0 Measurement rate is slow
1 Measurement rate is fast
REMS Remote without Lockout
Places the instrument in the remote mode, lights the front panel REM annunciator,
and only two front panel keys are active (with special REMS functionality):
The Q key triggers a single scan.
The K key returns the instrument to normal front panel control.
To return the instrument to normal front panel control with a command, use the
LOCS command.
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 at any time, except during the measurement portion
of the scan internal. only at the completion of any scan in progress. Clearing the
Review array also clears ALARM OUTPUTS and DIGITAL I/O lines to a logic high..
*RST Reset
(See front of table.)
RTD_R0 RTD Ice Point (R0)
For the indicated channel, store the numeric data as the RTD R0 ice point
resistance, i.e., the resistance of the RTD at 32°F (0°C). Changing the ice point also
clears the Review array and ALARM OUTPUTS and DIGITAL I/O lines. (The 0
portion of R0 in the RTD_R0 command is the number zero.) The default value is
100.00.
RTD_R0 <channel<, <R0>
<channel> = 0,1,2 ... 20
<R0> = 000.00 to 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.
Example: RTD_R0 6, 124.85 [For channel 6, set the R0 ice point resistance to a
value of 124.85.]
