The mirrin multi channel load logger (mll) measures ac rms current (load) up to four channels and is ideal for monitoring loads on circuits and switchboards to record load profiles and used to identify slow changing events such as long duration interruptions, outages and derive estimates of usage patterns. The mll is also useful as a diagnostic tool to assess load sharing on single phase circuits and load balancing on three phase systems. The mll incorporates a liquid crystal display (lcd) which shows the maximum current measurement in each channel together with the date-time stamp of its occurrence and therefore ideally suited as a maximum demand indicator (mdi). Key hardware features log channels: four current (standard) and two temperatures (optional). current sensors comply with cat iv 600v. programmable logging interval starting from one second. programmable alarms for current and temperature channels. Alarm events listed in a table. over two years memory at ten minute logging interval (sd card included). displays load current, maximum demand and maximum temperature with a date-time stamp for each channel. battery (rechargeable) operated with power saving mode to extend battery life. external dc and solar charging. rated at ip65. Suitable for indoor and outdoor applications. communications with devices that incorporate bluetooth and or wifi. accessories various flexible current sensors. various clamp-on current probes. temperature probes: ambient and surface temperatures.
