SMODE [xxxx] where xxxx = STOP, RUN, POLL or SEND VAISALA _______________________________________________________________________ 35 User's Guide ______________________________________________________________________ Example: >smode Serial mode > : STOP ?POLL Table 13 Mode STOP RUN POLL Selection of Output Modes Output Only with the SEND command Automatic output Only with the SEND [addr] command Available Commands All (default mode) Only command S Use with RS-485 buses Selected output mode will be activated after power outages. INTV Use the INTV command to set the outputting interval for the RUN mode. The default value for this command is 2 seconds. INTV [xxx yyy] where xxx = yyy = Output interval (0. . . 255) where 0 is the fastest possible output rate. Unit (s, min or h) Example: >intv 1 min Interval > : 1 min 36 __________________________________________________________________ M210912EN-B Chapter 4 ________________________________________________________________ Operation Data Filtering The commands introduced in this section are used for setting the filtering level, checking the probe configuration, listing available commands and possible error messages, and displaying the software information of the probe. FILT [0. 1. . . 1] Use the FILT [xxx] serial line command to set the filtering level. The output is calculated based on the following formula: [( new result * filt) + ( old result * (1. 0 - filt))]. FILT [xxx] where xxx = 0. 1. . . 1 where 1. 0 = no filter and 0. 1 = about 16 moving average Example: >filt Filter > : 0. 800 ? ? Use the ?serial line command to check the current probe configuration. command is similar but can also be used if the probe is in POLL mode.
