24AUTOWhen analyzing samples using an autosampler, the MARK IN signal, input tothe detector from the autosampler at the time of sample injection, causes amarker to be overlayed on the chromatogram and auto-zero to be executed.The chromatogram base is therefore set to zero.MANUALAuto-zeroing is not executed when a signal is input into the MARK IN terminal.The auto-zeroing operation is only executed when the [AUTO ZERO] key ispressed.Note: The [MARK] key function on the front panel causes a markerregardless of this setting.AUTO ZEROAUTOAUTO ZEROAUTO(MANUAL)Input screenFlashes[MONIT] [SHIFT] [3]Auto-zero setting screen[EDIT/ENTER](MANUAL)is the setting after the change.[ ][ ][EDIT/ENTER]S T(AUTO or MANUAL can be selected)Normal operation mode monitor screenNORM 64 STD-0.0 + OFFTEMP: xx.x/yy °C-0.0 + OFF[MONIT] SSFigure 5.2 Setting for Automatic or Manual Auto-zero ExecutionNote: The AUTO setting is convenient for analysis, whereas the MANUALsetting is convenient for fractioning.5.4 Zero point shift for integrator output ([SHIFT][4])The allowable input voltage range of a current integrator is, in general, -10mV~ +1V. The dynamic range on the negative side is therefore small compared tothat on the positive side. When the output level is shifted beforehand to thepositive side using the zero point shift function, integrator output can beprevented from falling below -10mV.When [AUTO ZERO] is operating or when a signal is input into A/Z IN on theback panel, integrator output size of 0, 5, 10, 50, or 100mV can be selected. |
