3 Operation Model 6600

•Use the Curve Algorithm to linearize output. (Refer to programming section, or contact factory.)

•Zero. Used to set up a zero calibration.

•Span. Used to set up a span calibration.

•Alarms. Used to set the alarm setpoints and determine whether each alarm will be active or defeated, HI or LO acting, latching, and/or fail-safe.

•Range. Used to set up four analysis ranges that can be switched automatically with autoranging or used as individual fixed ranges.

Any function can be selected at any time in the analyze mode (unless password restrictions apply). The order as presented in this manual is appropriateforaninitialsetup.

Each of these functions is described in greater detail in the following proce- dures. The VFD screen text that accompanies each operation is reproduced, at the appropriate point in the procedure, in a Monospaced type style.

3.3The System Function

The subfunctions of the Systemfunction are described below. Specific proceduresfortheirusefollowthedescriptions:

•Dig_Filt: Adjust how much digital filtering should be on the signal

•SELF-TEST:Performs a self-diagnostic test to check the integrity of the power supplies, outputs, detector signal and preamplifier.

•PWD: Login security system for accessing to the setup functions.

•LOGOUT: Prevents an unauthorized tampering with analyzer settings.

•AUTOCAL: Set the automatic calibrated timer schedule for Zero and Span cycling.

•HMGNZR: Turn Ultrasonic homogenizer ON and OFF on the analyze mode.

•TRACK: Set the system reading to be held or followed by the concentration“gasorfilter”duringcalibration.

•CAL-HOLD-TIMER:Set the timing for calibration holding and timing for the sample reading after return to analyze mode.

•ALGORITHM: Linearize the output for nonlinear characteristic.
