4.8 Set the measurement logging interval (2- or 4-channel analyzers)
Set the measurement logging interval. Measurements are saved to the data log at the measurement
logging interval. In addition, the relays and analog outputs are updated at the measurement logging
interval.
1. Push menu, then select SETUP SYSTEM > CONFIGURE ANALYZER > MEASUREMENT >
SET MEASURE CYCLE.
2. Select and configure each option. Select SEARCH STABILITY first.
Option Description
SEARCH Between channel measurements, the analyzer rinses the measurement cell
STABILITY with sample from the next channel to be measured for a set time interval (or
until the measurement is stable).
NO (default)—Sets search stability to off. The analyzer rinses the measurement
cell for a set time interval. As a result, the measurement logging interval is
constant.
When SEARCH STABILITY is set to NO, the settings to configure are CYCLE
TIME and ON LINE MEASURE time.
YES—Sets search stability to on. The analyzer rinses the measurement cell
only until the measurement is stable, which minimizes the rinsing time. As a
result, the measurement logging interval is variable.
When SEARCH STABILITY is set to YES, the settings to configure are MAX
CYCLE TIME (maximum measurement logging interval) and ON LINE
MEASURE time.
ON LINE Sets the amount of time the analyzer measures the channel (1 to 119 minutes,
MEASURE default: 10 minutes).
Note: The analyzer measures the channel continuously during the ON LINE MEASURE
time. The measurement shows on the display. At the end of the ON LINE MEASURE time,
the analyzer saves the average measurement for the last minute to the data log. In
addition, the analyzer updates the relays and analog outputs so they represent the saved
measurement.
MAX CYCLE Note: The MAX CYCLE TIME option only shows when SEARCH STABILITY is set to YES.
TIME
Sets the maximum measurement logging interval (11 to 120 minutes, default:
45 minutes). Sets the maximum rinsing time. For example, if the MAX CYCLE
TIME setting is 45 minutes and the ON LINE MEASURE setting is 10 minutes,
the maximum rinsing time is 35 minutes.
CYCLE TIME Note: The CYCLE TIME option only shows when SEARCH STABILITY is set to NO.
Sets the measurement logging interval (11 to 120 minutes, default: 45 minutes).
Sets the rinsing time. For example, if the CYCLE TIME setting is 20 minutes
and the ON LINE MEASURE setting is 10 minutes, the rinsing time is
10 minutes.
Measurement logging interval = CYCLE TIME
CYCLE TIME = ON LINE MEASURE time + Rinsing time (set value)
Measurement logging interval = ON LINE MEASURE time + Rinsing time
(variable)
