ZOOM BUTTON
In the various modes the un-zoomed rst line of information is presented with the rst word in reverse video
(white on black) we shall refer to this as the “cursor”. “Click” the Zoom button and the cursor will toggle to the
next line, “hold” the Zoom button to magnify the information contained in the cursor line to double size
allowing it to be read easily. “Click” the Zoom button whilst in the magnied mode to toggle through each line in
sequence. “Hold” the Zoom button to revert the screen back to un-zoomed – or simply “click” the Menu button
to un-zoom the screen and change to the next mode in one step.
RUN BUTTON
Click the “Run” button to start stop or pause a measurement period, “Hold” the Run button to erase all the
data, a message prompts “clear all data Yes/No ?”, selecting Yes clears all the stored data.
When the meter is running (during a measuring period) the top right hand corner of the display has a ashing
activity icon. When paused a “II” symbol is displayed. After the PML has been reset the activity icon is not
displayed until the Run button is pressed again to start a new measurement period.
ENTERING COST AND GREENHOUSE GAS INFORMATION.
When in the COST screen mode, “hold” the Menu button until the Set Cost screen appears.
Click the Zoom button to change the ashing number, click the Run button to select the next digit and so on.
When nished setting the cost, click the Menu button to exit the set up mode.
When in the G/GAS screen mode, hold the Menu button until the Set G/GAS screen appears, enter the
Greenhouse Gas value in a similar fashion as for entering cost in the previous step.
When nished setting the G/GAS, click the mode button to exit the set up mode.
SETTING OR CHANGING THE MEASUREMENT PERIOD.
When in the RUNTIME/ENDTIME screen mode, hold the Menu button until the SET TIMER screen appears.
Click the Zoom button to select the desired run time. If no period has been selected ( Timer Duration Not Set)
then when run, the PML will count time upwards continuously until manually stopped.
When a RUNTIME period has been selected (1,8,12 & 24 hours or 2,5,7,14 & 28 days), pressing “Run” will load
the timer with the selected run-time and the displayed time will count downwards until zero is reached causing
the meter to stop. Note it is best to stop and clear the Meter before setting a new Runtime.
When nished setting the desired RUNTIME, a short press of the Menu button will exit the set up mode.
When time is counted up the Timer screen is labelled RUNTIME as it shows the actual elapsed
time, or when counting down it is labelled as ENDTIME or the time remaining for the measurement.
STARTING A MEASUREMENT PERIOD
Before starting a new measurement period, always clear all the old data from the meters’ memory. Press and
hold the Run button until prompted “ ERASE ALL DATA NO?/YES?, press the button under the “Yes” prompt to
clear all the old data (or select No to retain the data).
When the meter is running during a measurement period it is OK to “click” the Menu button to change through
the various modes to view the data in real time, or to use the Zoom button.
If the appliance being measured is cyclic in nature ie it starts and stops automatically, such as a fridge or similar
thermostatically controlled device, the data for estimated cost, greenhouse gas and energy will be more
accurate if measured for a longer period. For continuous cyclic appliances such as a fridge it is best to measure
over a 24-hour period (or a longer complete multiple of 24-hour periods).
SCREEN BACK-LIGHT
The screen back-light is automatically turned off after 30 seconds but will be turned on again for another 30
seconds if any of the buttons are pressed. The best button to use, if you do not want to change modes or start /
stop the unit, is the Zoom key.
When the back-light is off the rst click of the Zoom key does nothing except turn on the backlight,
of course pressing the Zoom button whilst the back-light is on will toggle to the next line of data as usual.
