5. Description
Digital multimeter E is a robust, battery operated
multimeter with a 3½-digit LCD display for
measuring voltage, current and resistance as
well as for diode and hFE gain testing.
All measurement ranges are selected by means
of a rotary dial. All measurement ranges are
protected against overload except the 20 A
range.
The meter is equipped with a hold function,
negative polarity indication, over range indica-
tion, low battery indication and automatic switch
off after 15 minutes. After the power is automati-
cally switched off it needs to be turned off and
turned on again to continue the power.
The digital display is folding for ease of reading
and on the backside there is a fold out prop for
standing the device on a table.
6. Operation
Note
The multimeter switches into an indeterminate
state if the Hold button is activated (Hold func-
tion button (8) pressed). After it is switched on,
the display will then show "1.666" (where the
position of the decimal point is dependent on the
selected measuring range). If this case should
arise, deactivate the Hold function while the
equipment is switched on (deactivate Hold func-
tion by pressing the button one more time).
