INTRODUCTION
WARNING
These safety warnings are provided to ensure the safety of personnel
and proper operation of the instrument.
• Readtheinstructionmanualcompletelyandfollowallthesafetyinfor-
mation before attempting to use or service this instrument.
• Neverexceedthemaximumworkingvoltageratingsgiven.
• NEVERopenthebackoftheinstrumentwhileconnectedtoanycircuit
or input.
• Always inspect the instrument accessories and leads prior to use.
Replace any defective parts immediately with factory parts.
1.1 International Electrical Symbols
Signifies that the instrument is protected by double or reinforced insulation.
Indicates a WARNING and that the operator must refer to the user manual for instructions
before operating the instrument. Failure to follow or carry out any instructions preceded
by this symbol in the user manual may result in personnel injury or damage to the
instrument and installations.
Risk of electric shock. The voltage at parts marked with this symbol may be dangerous.
Refers to a type A current sensor. This symbol signifies that application around and
removal from HAZARDOUS LIVE conductors is permitted.
Refers to a type B current sensor. Do not apply around or remove from HAZARDOUS
LIVE conductors without additional protective means (de-energizing the circuit or
wearing protective clothing suitable for high voltage work).
In conformity with WEEE 2002/96/EC

PRODUCT FEATURES
2.1 Description
The Simple Logger®II Model L261 is a one channel recording device
powered by an alkaline battery pack. Line tracking is performed such that
64samplesoveronelinecyclearetaken.Frequencytrackingisperformed
over the range of ±2Hz around the nominal line frequency (50 or 60Hz).
Harmonic measurements are calculated from these 64 samples (Harmon-
ics are only available from the Simple Logger®IIControlPanelwithinthe
DataView®application).
The Simple Logger®II records TRMS at a rate of up to eight times per
second. The measurement process is performed no more than eight times
per second. TRMS calculations are performed on a single line cycle. This
means that the input(s) are ignored between measurement intervals.
The main advantage of the logger is its ability to perform a variety of
recording tasks with easy and intuitive setup from a computer using
DataView®software.
Analog information on the input is sampled and converted to a digital
signal. This digital signal is processed and stored along with scale and
time information. An optically isolated Universal Serial Bus (USB) port
provides for the transfer of data from the instrument’s internal memory
to the computer for analysis. Figure 2-1 shows a block diagram of the
logger.

Storage Rate Programmable from 125mS to 12 hrs
Storage Modes Start/Stop, FIFO and Extended Recording Mode* (XRM™)
Recording Length 1 minute to 8 weeks, programmable using DataView®
Memory 240,000 measurement (512KB)
The recorded data is stored in non-volatile memory and will be
retained even if the battery is low or removed.
Communication USB 2.0 optically isolated
Power Source** 2x1.5V AA-cell alkaline batteries
Battery Life 100 hours to >45 days
(dependent on sample rate and recording length)
*This unique recording mode provides the opportunity to continuously record over long periods
of time by reducing the stored sample resolution of the oldest data and maintaining matching
resolution for the newest data. Each time the memory lls up using XRM™, every other of the
oldest stored samples is discarded making room for newer samples. This process continues
until the recording is manually stopped.
**A memory backup capacitor provides backup power while the batteries are being changed.
This backup capacitor will maintain the instrument for up to 10 seconds without batteries
installed. After 10 seconds the date, time and conguration will need to be reset (no data will
be lost). If the unit is connected to DataView®via a PC, the battery life is 100 hours regardless
of the storage rate.
