Types of measurement

Types of measurement

PicoLog can log up to 250 different types of measurement at the same time from up to 20 converters. These measurements can be made up of a variety of readings:

Single readings, normally in volts, measured by a converter

Multiple values obtained by analysing a set of converter measurements, for example, AC voltage or frequency

Calculated values derived from one or more converter measurements, for example, power calculated from amperes x volts

Values obtained from a set of readings take some time to measure, so they can only be used in Real time continuous mode, when the sample time is greater than QuickSampleMs.

Measurements are added by first selecting a converter, then specifying what the channels on the converter are to be used for. Different converters have different settings, so the dialog boxes to set up a measurement are different for each converter. The fast converters have three different dialog boxes: one for real time mode, one for block mode and one for streaming mode.

The following options apply to all converters:

Parameter options: range, unit and decimal place preferences

Alarm settings

Signal Conditioner options

Parameter scaling: scaling for other types of sensor, using table lookup or equations
