MODEL 1992 SCANNER OPTION CONTACT CONFIGURATION: 8-channel 2-p Mode A/V L RATIO *L L 2 POLE 4 POLE MANUAL: A!lows channel to be manuaJly closed with SCANNER key. STEP: lnaements one channel perintenral or trigger, SCAN: Scans one set of channels per interval or trig- ger (minimum time between channels). ON: Channels 2 through 8 referenced to channel 1. OFF ? ? ? ? ? ? ? ? ? Range changes will restart at channel 1. ? In MANUAL, at least one reading must be taken on channel 1 before at- tempting to display ratio on channels Z-8. ACTIVATING THE SCANNER SCANNER followed by number (%3) activates the scanner. - In MANUAL, channel number selects channel to be dosed. ? In STEP or SCAN, number selects channel limits and starts scanning process. STOPPING THE SCANNER (opening au aam see manual). * Scanner switching is break-before-make. The time required to change channels is approximately 17rwc. which includes break-before-make relay time settling time. ? When using the scanner with ACV or ACA, a DELAY time must be programmed to accomcdate AC converter settling time (typically lsec).
