The ESCOLA 100 may NOT be used
to measure directly at low-voltage
mains sources. See page 2 of "Meas-
urement categories" as specified in
DIN EN 61010-1.
The nominal voltage of the voltage
source may not exceed 600 V.

10A
CAT III 600V
If measurements are made when the magni-
tude of the variable is unknown, always select
a large measuring range before shifting down
to lower ones.
Connect the common/ground lead first and
only then the signal lead.
For measurements of voltage up to 100 mV,
set the rotary switch to the range 0.1
mA/100 mV.
9.1 DC voltages up to 600 V:
Set the four-way switch to
Alternatively, if measurements are to be made
with the zero point in the centre, then set the
four-way switch to
Select the required measuring range to a
range measured in V.
9.2 AC voltages up to 600 V:
Set the four-way switch to
Select the required measuring range to a
range measured in V.

11. Measuring current and voltage together
The ESCOLA 100 may NOT be used
to measure circuits connected directly
to low-voltage mains sources. See
page 2 of "Measurement categories"
as specified in DIN EN 61010-1.
The nominal voltage of the current
source may not exceed 600 V.
The multimeter is to be connected
in series with the load on the side
where the voltage with respect to
ground is lowest!
Turn off the circuit before the Es-
cola 100 meter is connected into
it.

11.1 DC voltages and currents:
Set the four-way switch to
Use the rotary switch to set the desired volt-
age measuring range and read off the meas-
urement.
Set a suitable current measuring range and
read off the measurement.
11.2 AC voltages and currents:
Set the four-way switch to
Use the rotary switch to set the desired volt-
age measuring range and read off the meas-
urement.
Set a suitable current measuring range and
read off the measurement.
