- *1 In high-speed logging mode, data is recorded in 83 ms at 60 Hz and in 100 ms at 50 Hz.
- *2 Instantaneous power and cumulative power consumption are calculated using the measured current and set voltage/power factor. Make sure to correctly set the number of channels used, applicable circuit, CT type, frequency, voltage and power factor.
- *3 In sleep mode, the display turns OFF after 10 seconds with no operation, and will turn ON with button operation. LAN cannot be used when sleep mode is specified.
- *4 LAN cannot be used when high-speed logging mode is selected.
- *5 Automatically writes data to the SD card upon reaching the upper limit of the internal memory, and continues recording up to the upper capacity limit of the SD card. If the SD card is not recognized or write protection is enabled, recording will stop when the upper limit of the internal memory is reached. (Data can be output to the SD card by pressing the button after inserting the SD card.)
- *6 This mode always records the latest measured values for the upper limit of the internal memory. (When the upper limit of the internal memory is exceeded, data items will be overwritten beginning with the oldest data item.)
- *7 An alarm sounds when the cumulative power upper limit set in the threshold setting mode is exceeded. Alarm output is not available while in sleep mode.
- *8 If using an SD card from another manufacturer (compatible with SD/SDHC card standards), data integrity cannot be guaranteed, as, depending on the SD card, there may be cases in which the card is temporarily able to read and write data but cannot be recognized correctly during use. Please use the recommended SD cards with this product.
- *9 Nickel‑metal‑hydride batteries and alkaline batteries can be used. Manganese batteries cannot be used.
- *10 Battery life may vary depending on the measurement environment, recording interval, measurement mode and battery type/performance.
- *11 Conditions: 2 AAA nickel‑metal‑hydride batteries; sleep mode; continue mode; 1‑s recording intervals; SD card use (HMC-SD291); ambient temperature of 23°C; auto range switching OFF; alarm output not in use.
- *12 If using the mounting magnets, install the product in a location in which it will not be subject to impact.
- *13 Mounting magnets are shipped already installed on the product by factory default.
- *14 The included connector is Model XW4B-02B1-H1.
- *15 Please make sure to use the AC adapter included with the product.
