Manual Selection Of The Measuring Range - Monacor ZM-100 Manual De Instrucciones

4) Always switch off the meter after operation, otherwise the batter-
ies will be consumed unnecessarily .
If the meter is not used for a longer period, the batteries should
be removed to prevent any damage to the meter in case of battery
leakage .
5 Measurements
Make sure that the speaker or the speaker line to be measured
is disconnected from the amplifier!
1) Connect the test leads to the two jacks (7) . The polarity is insig-
nificant in this case .
2) Hold /clamp the test tips /clamps of the test leads to the speaker or
the speaker line .
3) Read the measured values . Starting from the highest measuring
range, the meter will automatically select the most suitable range .
The display will show the operating mode "Auto" (3), the measur-
ing range selected (2), the impedance Z measured (5), and (except
for the measuring range 200 kΩ) the calculated power (6) which
the speaker or the speaker line would consume at a 100 V system .
If "– – – –" is displayed at (5) instead of an impedance value,
the impedance measured is greater than 200 kΩ and cannot be
indi cated . This may also be caused by contact problems . Check
the con nections .

5.1 Manual selection of the measuring range

To switch off the automatic range selection and to select a given
meas uring range, press the button RANGE (9) .
At (3), "Man ." will be displayed, and at (2), the measuring range
"200 kΩ" will be indicated .
When pressing the button RANGE repeatedly, you will return via the
measuring ranges "20 kΩ", "2 kΩ", and "200 Ω" to the automatic
range selection ["Auto" will be displayed at (3) again] .
