The MR6000 overcomes all barriers to reach new ground and meet challenges that are yet to be seen. World class specifications, operability and design - Hioki’s newest memory recorder has been re-engineered from top to bottom, delivering unprecedented performance that will change how you look at waveform recording.
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.
Applicable products: 3541, RM3542, RM3543, RM3544, RM3548
1. The measured values are abnormal.
2. The instrument display shows “----.”
3. The instrument display shows “OF.”
Causes and solutions
1. There is a wiring break in the test leads. → Replace the test leads.
*Test leads that have been bent frequently in the past may develop a break in their wiring.
2. The test leads are not connected properly. → Connect the test leads properly.
3. The 3554’s fuse has blown. → Replace the fuse.
4. Zero-adjustment has not been performed properly. → Perform zero-adjustment properly.
5. An appropriate range has not been selected. → Select an appropriate range with the instrument’s range button.
6. The tip of the pin-type lead is damaged. → The tip pin on the 9465-10 and 9772 (9465-90/9772-90) is user-replaceable.
Current and active power: DC and 45 to 66 Hz frequency range
Power factor effect (active power with a low power factor): 45 to 66 Hz frequency range
In other frequency ranges, the 3390-10 delivers the same level of accuracy as the 3390 used with the CT6862, CT6863, or 9709.
High accuracy is guaranteed when used in combination with the CT6862-10, CT6863-10, and 9709-10. High accuracy is only guaranteed when these sensors are used in combination with the 3390-10.
Connecting the voltage terminals to the load
Power measurements will include loss from the voltage input terminals’ input resistance. Loss due to the instrument can be minimized when the measured voltage is low and the measured current is small.
Connecting the current terminals to the load
Power measurements will include loss from the current input terminals’ input resistance. Loss due to the instrument can be minimized when the measured voltage is high and the measured current is small.
When using clamp-on sensor input, the sensor’s loss can be ignored for the most part.
*CAT III: A circuit from the primary side of a device (fixed equipment) drawing electricity directly from a distribution panel or from a distribution panel to an outlet
Constant-voltage method: The current is given by the resistance value being measured and the internal circuit’s reference resistance value and protective resistance, and it varies with the measurement voltage that is applied. I = Measurement voltage / (Reference resistance + protective resistance + resistance being measured)
Constant-current method: A constant current flows to the resistance being measured, and the resistance value is calculated from the resulting voltage drop. Measurement currents for individual ranges can be checked in the product’s user manual.
• The inverter may be displaying the primary-side current value.
• The value may be affected by inverter noise and harmonics.
• The difference may derive from the difference between RMS (true RMS) and MEAN (average rectified) measurement. (The 3285 uses RMS.)
Many utilities charge industrial and commercial customers a power factor penalty when their equipment draws power that is not put to its full use due to various factors such as non-linear loads or the use of induction motors that inherently [...]
