How to insert or replace the removable battery of LSM meter
DANGER OF ELECTRIC SHOCK!
Do not touch the battery or battery
terminals with bare hands.
Use the holding tool for inser-
ting or removing batteries.
1) Remove the screw which is holding the removable battery cover
and take off the battery cover.
2) Pick up the battery holding tool supplied by LUNA and take the
previously inserted battery out if available by holding with the tool. Do
1.10.22. Neutral Measurement
LSM series meters can optionally support detection and recording of
neutral current events. When the magnitude of the neutral current is
measured at least 0.5A greater than the magnitude of the vectorial
sum of phase, neutral current event records its beginning time and the
neutral current miss-match icon ‘n’ is blinked on the LCD of the meter
during the event. When the neutral current event ends, its end time is
recorded and its counter is incremented. The start-end time of neutral
current events can be read using the OBIS codes of 96.77.9*1,...,10.
The total number of neutral current events can be read with OBIS
code of 96.77.60.
1.10.23 Demand Reset Button
Manually performs month-end operations, resets demand. With this
button, the past month information about invoice periods can be gi-
ven. Example 1.8.1 * 1 The OBIS value indicates the T1 consumption
rate for the previous invoice period.
1.10.24. Harmonic Measurement
LSM series meters can optionally measure the total harmonic distor-
tion (THD) for voltage and current. The voltage THD values for R, S,
T phases have OBIS codes of 32.7.1, 52.7.1, 72.7.1; the current THD
values for R, S, T phases have OBIS codes of 31.7.1, 51.7.1, 71.7.1
respectively. They can be read by their corresponding OBIS codes
and can optionally be displayed on the LCD of the meter.
1.10.25. Removable Battery
LSM meters optionally support removable battery feature. If the meter
includes this feature, it requires the removable battery inserted to fully
work when ac power is not available. When the removable battery of
the meter is removed, the meter displays “BATT OFF” message as in
Fig. 1
for 4 seconds and then turns off itself. In this state, the meter
doesn’t wake up by pressing its menu button; it only wakes up when
the ac power is connected. After the removable battery is inserted, the
meter wakes up displaying “BATT ON” message and the measured
removable battery voltage on its screen as in
Fig. 2
for 4 seconds. In
this state, the meter is able to wake its screen by pressing its menu
button.
