1 Getting Started
1.1 Brief
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 that can be 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).
The MLL is generally asleep and wakes up four times a second (every 250ms) and takes a
measurement by sampling the input at 1600Hz. The aggregated measurements are
committed to memory (logged).
The maximum current reading is based on the instantaneous readings with a sixty-second
exponential time constant.
The MLL is housed in a small light-weight polycarbonate weatherproof box.
1.2 Feature summary









Logs four (4) current channels (standard) and two (2) temperature channels
(optional);
Programmable logging interval, minimum one second;
programmable alarms;
Over two years memory capacity at 10 minute logging interval (8GB SD card
included);
Displays the maximum demand and maximum temperature with a date-time stamp
for each channel;
Bluetooth enabled for Android devices that provides for online measurements,
graphical displays and options to download data and email;
Battery operated with power saving mode to extend battery life to near 12 months;
Facility for external DC power source including solar charging; and
Suitable for indoor and outdoor applications.
1.3 Power up
The MLL will power up and enable logging only when it detects a current sensor connected
to one of the four terminals. This is intended so that battery energy is better conserved when
not in use. The MLL will still power when energised via the communications cable but will not
commence logging.

1.6 Power modes
The unit detects its available power source and automatically switches to Sleep Mode if the
power source is internal batteries. In this case, during normal operation, the LCD is blanked
and Bluetooth disabled. Measurements are performed in the background. The LCD and
Bluetooth are active for sixty (60) seconds when the button is pressed.
If the unit detects external power (via Port) then the LCD and Bluetooth remain permanently
enabled.
1.7 Internal batteries
The MLL is powered by two non-rechargeable 'AA' cell lithium batteries or a rechargeable
battery pack supplied by the manufacturer.
Recommended ‘AA” size batteries include:
 Energizer® Ultimate Lithium AA Batteries; and the
 Alternative is the Varta Professional Lithium AA - Mignon (6106-1.5V).

1.8 Current sensors
The MLL is designed to interface to voltage output current sensors, which is standard with all
flexible current sensors provided by CHK Power Quality Pty Ltd.
It is also possible to utilise the existing clamp-on current sensors (100A, 500A and 1000A)
as provided for the MaxiAmp unit. This will require an adaptor for each.

The hysteresis level amount applies equally to the upper and lower limits. The
minimum duration time applies equally for entering and existing alarm states.
2.5.4 Temperature channels
Checking the Log External Temperature box will enable the log of Temperature
channels. This option is not available in models that do not support external
temperature channels.
2.5.5 Total harmonic distortion (THD)
Checking the Log Current THD box will enable the calculation and log of THD.
2.5.6 Memory card
An SD Card is usually fitted to expand the base memory. If the unit is fitted with an SD
card then the Use SD Card box will be ticked. There is no option for the user to alter
this setting.
2.5.7 Display time option for maximum value
The unit normally displays the maximum value with a time stamp of its occurrence.
Checking the Show time since maximum on LCD will instead show the elapsed time
from when the maximum occurred.
2.5.8 Power saving mode
Ticking this box reduces the normal sampling of four cycles per second to one cycle
per second and hence extends internal battery life by up to three times longer.

4 Operation
4.1 Field installation procedure
Step 1: The MLL should be installed in accordance with appropriate Live Installation
instructions and procedures.
The MLL has a flanged box with holes at the top and bottom (see photo below - figure 4.1.1)
for pole pin or hook. Mount the MLL on a pole pin when used on overhead mains and on a
hook in kiosks or sub-stations. In both cases secure the MLL with a lanyard.
Figure 4.1.1
Step 2: You can connect any current sensor to any of the four input channels at any time.
The MLL will automatically detect the type of current sensor to produce the correct current
reading.
Step 3: Activate the LCD and Bluetooth by pressing down on the “Press” button until the
display is shown. This takes approximately one second. Check that the heartbeat LED is
flashing blue. Also check that the instantaneous current readings on the display correspond
to expected readings.
4.2 Battery replacement
The batteries are accessed by unscrewing the four stainless steel screws on the top of the
unit and removing the lid. The battery holder is fitted on to the bottom PCB. Check that the
gasket is in good condition and seated correctly in the groove of the lid before fitting the lid.

5 Service and Support
5.1 Calibration
The MLL is factory calibrated. Calibration of the MLL is recommended every thirty six (36)
months.
5.2 Equipment maintenance
Enclosure of the MLL should be inspected for mechanical damage leading to cracking in the
case. The integrity of the lid seal should also be inspected.
5.3 Cleaning and decontamination
The case of the MLL can be cleaned with a cloth moistened with Isopropyl Alcohol. There
are no decontamination issues.
5.4 Technical support
We provide complementary technical support. Please contact our Technical Services
