Logging (LAN-connected instruments)

以短至1秒的时间间隔记录多达512个通道

Take advantage of LAN speeds to log up to 512 channels at an interval as short as 1 s.
Display of the latest values is updated in real time (up to 32 channels).
Automatically output CSV files and daily/weekly/monthly reports.

Display a graph of up to 32 channels in real time.

Example uses

Surveying energy savings in air-conditioning/boiler equipment

Realize accurate measurement while reducing trips to the field and shortening measurement times.

Monitoring an intermittent leakage current from a distant location

Ascertain when leakage currents occur. This capability is ideal when you need to find a problem’s cause.

Viewing logging data from a distant experimental site from your lab

You can view measurement data from a distant experimental site or facility with restricted access from your lab. This capability has won customer praise for speeding up research.

Measuring power, temperature, and humidity simultaneously and monitoring them remotely

Monitor data from your office without visiting measurement sites.

Surveying the load before updating power distribution equipment

Monitor fluctuations in load current for branch circuits remotely so that you can redesign electrical equipment efficiently.

Features

This function lets you acquire measured values from LAN-connected instruments and monitor them (numerically) in real time or display them as a graph.

Log up to 512 channels at an interval as short as 1 s.

Functionality for searching for instruments on your LAN makes it easy to connect.

Select the channels to log from connected instruments.

Search for instruments on the LAN to connect easily.

Maximum number of connected instruments	30 instruments
Maximum number of channels	512 channels + 16 channels (inter-channel calculation channels)
Logging Interval	1 / 2 / 5 / 10 / 30 s, 1 / 2 / 5 / 10 / 30 min, 1 hour (The application determines the minimum logging interval by measuring the time for getting measurement values of selected channels.)

Select up to 32 measurement channels for inclusion on monitor and graph displays.

Display of these values is updated in real time.

Performs calculations using measured values. The results are logged.

Calculations are performed using measured values, and the results are logged.

Example uses

Converting sensor input into a physical property
Totaling energy values for individual branch circuits

Numerical value	Channels or constants
Basic arithmetic operations	$+$ , $-$ , $\times$ , $\div$ , brackets
Basic operation	Absolute value, square root, cube root, power
Trigonometric function	$sin$ , $cos$ , $tan$ , $arcsin$ , $arccos$ , $arctan$
Exponential functions, logarithmic functions	$exp$ , $log_{10}$ , $ln$
Rounding	Round up, down, or round to the specified number of digits

Automatically outputting CSV files and daily/weekly/monthly reports

Logging values can be automatically output as a CSV file on a regular basis or output as a daily, weekly, or monthly Excel report.

Automatic CSV output

Outputs detailed information, statistical values, and measured values for all channels on a daily or hourly basis. The file format is CSV format.

Output contents	Description
Channel Information	Instrument, serial number, channel name, measurement start time, stop time
Statistics	The average/maximum/minimum value of each channel during the period from the start of measurement to the stop. Time at which the maximum and minimum values occurred.
Measured value	All logged measurements

Automatic Report Output

The measurement data is totaled and automatically output as a daily / a weekly / a monthly report in the pre-defined report format. The file format is PDF or Excel.

Report contents		Description
Instrument information		List of measuring instruments
Channel Information		Detailed channel information
Measurement data	List	Table of average / maximum / minimum values for each channel at time intervals (). () 30min. or 1h. for a daily report. 1day for a weekly or monthly report
	Graph	Graph of measurement data list. The average, maximum and minimum values for each channel are combined into a single graph. Three graphs (for three channels) are output per page.
	Demand list	Tables totaling each channel, effective electric energy, electricity rates, and CO2 equivalent (*) Only when output is selected for the measurement items such as electric energy, demand amount, and demand value of PW3360, PW3365, PQ3100, and PQ3198.
