Data Storage

The logger captures Trend measurements. The following are definitions
of terms used in this section:
Input Channel: Source for the measurement channel of the instrument.
Measurement Channel: Measurement of input. This can be a simple
direct measurement, the result of complex mathematical operations on a
single or multiple input, or other channels.
Sample Rate: The rate at which the instrument measures inputs.
Storage Rate: The rate at which channel measurements are stored.

Trend Measurements

The logger stores the measurement of each of the inputs. In addition, the
user can define the storage rate, recording period and measurement
format using the Configure Instrument dialog box in the Simple Logger II
Control Panel software. Control Panel trend measurements are stored at
this fixed storage rate.

Logger Operation

When the instrument is in use, the following occurs (provided there is suf-
ficient battery voltage and no data is stored in the instrument s memory):
• The GREEN LED single-blinks every 5 seconds (STANDBY mode
is active and the logger is not recording).
• The RED LED is OFF, indicating there is no data in memory.
• The CONTROL button is used to Start/Stop a Recording Session.
• If the CONTROL button is not pressed for a period of one minute,
the instrument will enter SLEEP mode and wait for either another
button press or the recording start time to arrive (if a recording is
scheduled). While in SLEEP mode, the LEDs will not blink.
• A button press of 0.5 seconds will return the unit back to the
normal STANDBY mode.
