Viewing Recorded Measurements
Within the “LoGG-Stor“ function the measurements can be viewed directly on the
instrument display as well as through a computer (“Func-CYCL“ only allows for the data
to be viewed on computer). Press the ´SET/MENU´ key for 2 seconds: The first menu
displayed is now “rEAd-LoGG“ (read logger data). By then pressing the ´TARA´ key, the
last measurement recorded will be displayed; pressing the ´TARA´ key again scrolls
between the different values related to this data point. Pressing the ´MIN´ key or ´MAX´
key selects different data points.
6.4.2 “Func-CYCL“: Automatic datalogging with adjustable cycle-time
The Logger cycle-time is adjustable (see Configuration). For example, setting “CYCL“ =
60: A measurement is made every 60 seconds.
When the slow measurement “rAtE-Slo“ is chosen, additionally a low power function is
available: “Lo.Po“. If “Lo.Po“ is on, the device only will take a measurement at the point
of time of the recording. In between the recordings the measuring is not active. This
decreases the power consumption enormously and therefore is recommended for long
time recordings where no mains adapter is available.
Max. number of measurements: CPH62I0-S1: 10,000
CPH62I0-S2: 4,000
(at max. 64 recording sequences)
Cycle-time: 1 ... 3,600 seconds (=1 h),
selectable from the configuration menu
A measurement contains:
■ Slow measuring rate (rAtE-SLo):
- Sensor 1: current value at that data point
- Sensor 1: Min-Peak, Max-Peak since last data point
- Sensor 2*: instantaneous value at that data point
- Sensor 2*: Min-Peak, Max-Peak since last data point
- Instantaneous difference (Sensor 1 - Sensor 2)*: at that data point
- Min-Peak, Max-Peak of difference (Sensor 1 - Sensor 2)*: Min-Peak, Max-Peak
since last data point
■ Fast measuring rate (rAtE-FASt, -P.dEt):
- Sensor 1: average since last data point
- Sensor 1: Min-Peak, Max-Peak since last data point
- Sensor 2*: average since last data point
- Sensor 2*: Min-Peak, Max-Peak since last data point
- Average difference (Sensor 1 - Sensor 2)*: since last data point
- Min-Peak, Max-Peak of difference (Sensor 1 - Sensor 2)*: Min-Peak, Max-Peak
since last data point
* Only for 2-channel version CPH62I0-S2
