Data Acquisition (DAQ) | Oscilloscopes | Memory Recorders
The data is RECORDER function data with the extension ".rec". The time axis and sampling interval are set in the RECORDER function, and the time axis is selectable in 19 steps between 10ms/div and 1h/div. The time axis resolution is 100 points/div, so the resolution is 10ms when 10s/div is set.
Then, if you set 1ms for the sampling interval, there are 10 sampling data in 10ms (time resolution).
The RECORDER function records the maximum and minumum from these 10 sampled data, resulting in two values for each time.
Unfortunately, we are not in a position to recommend which Max or Min data should be used for your evaluation.
For your reference, the sampling interval is fixed at 1/100 of the time axis range in the MEMORY function.
(1/80 of the time axis range for the 8807 and 8808)
Please use the 9322 Differential Probe to record the waveform of a 400V AC power supply. It is also useful to measure the waveforms of high voltage like inverter output and PV systems, etc. Its maximum input voltage is 2000V DC /1000V AC (CAT II)/600V AC/DC (CAT III), and the output rate is 1/1000.
The normal input cord and 10:1 or 100:1 probes are dependent on the maximum rated voltage to the earth of the Memory HiCORDERs, but the 9322 offers CAT III 600V safety.
In addition to waveform recording, the 9322 has an RMS function and AC coupling function useful for detecting surge noise on a power supply circuit.
Please note that the MR8880 has a maximum rated voltage to the ground of CAT IV 300V / CAT III 600V.
Also, the maximum voltage between channels is 600V AC/DC, making it possible to measure a 400V circuit directly.

Is it possible to convert text data recorded on a Memory HiCORDER to binary format?
Unfortunately, text data cannot be converted to binary format, because the details of Memory HiCORDER settings are not available as text data.

Answer
Data Loggers | Multichannel Loggers
USB Memory
Use a USB flash drive.
USB Communication
Communicate with the LR8431-20 and initiate measurement using the Logger Utility software from a computer (using a USB cable).
USB Drive
Read files on a CF card that is connected to the LR8431-20 from a
computer (using a USB cable).
Data Loggers | Temperature Data Loggers | Compact Loggers
Save interval time: 1 sec. → 42.4 days
2 sec. → 84.9 days
5 sec. → 212 days
10 sec. or more → 1 year
If “All” is selected as the save parameter while using the 3P3W2M setting, the following save times are achieved:
Save interval time: 1 sec. → 16.1 days
2 sec. → 32.3 days
5 sec. → 80.7 days
10 sec. → 161 days
15 sec. → 242 days
30 sec. → 1 year
The maximum file size for measurement data is approximately 200 MB. When this amount is exceeded, a separate file will be created, and data will be saved in the new file.
Reference: The PW3360 series testers’ maximum recording time is 1 year.
Can I use the Wireless Humidity Logger LR8514 (Bluetooth) in China?
Bluetooth communication technology must be approved for use each country.
The LR8514's Bluetooth function is approved for use in China. Please refer to the specification of each model.
LR8514 (Please see Specifications.)

For your reference, the LR8410-30 is the approved model in the LR8410 series for use in China.
The LR5000 series uses non-volatile memory, so data remains in memory even if the battery is replaced or consumed.
LR5001, LR5011, LR5021, LR5031, LR5041, LR5042, LR5043, LR5051, etc.
Or, you can use the black spray or tape having known emissivity.
LCR Meters | Impedance Analyzers | Capacitance Meters
Connect the Hpot and Hcur to the shield of the coaxial cable, and connect Lpt and Lcur to the core wire. Impedance is measured by opening the one side to obtain [Zo] and shorting the other side to obtain [Zs]. Then, the impedance characteristics is calculated with the formula Z=√(ZoZs).
