5. General information
5.1 General information on the multimeter
5.1.1 The digital display
is a 3½-digit LC display with a font size of 16 mm
and a decimal point. The highest numerical value to be displayed is
2000.
5.1.2 The polarity indication
works automatically. Only a polarity contrary
to the jack definition is indicated with “-“.
5.1.3 The range exceedance is indicated by “ 0L“ or “- 0L“ and partly by an
acoustic warning.
Attention, no indication and warning in case of overload!
5.1.4 The „MAX/ MIN“ key function
4
automatically determines and stores
the highest and the lowest measured value. Preselect the measuring
range by means of the „RANGE“ key, if necessary. By pressing the key,
the following values are displayed:
„MAX“ shows the highest stored value and „MIN“ the lowest stored
value. The continuous determination of the MAX/ MIN value can be
stopped or started by pressing the „HOLD“ key
. By pressing the
„MAX/ MIN“ key for approx. 1 second, you can switch back to normal
mode.
5.1.5 The „RANGE“ key
6
is intended for shifting the manual measuring
ranges and masking the „AUTO“ symbol on the display at the same
time. Select the automatic range selection by pressing the key for ap-
prox. 1 second („AUTO“ is shown on the display).
5.1.6 Measured value storage „HOLD“: Press the “HOLD“ key
to store
the measuring result. At the same time, the display shows the “HOLD“
symbol. Press the key again to switch back to the measuring mode.
5.1.7 The nominal measuring rate of the ZA-TEC ZA 1-3 is 2 measurements
per second for the digital display.
5.1.8 The ZA-TEC ZA 1-3 can be switched on or off by means of the rotary
switch
. Switched off: position „OFF“.
5.1.9 The ZA-TEC ZA 1-3 switches off automatically after approx. 10 mi-
nutes (
APO
,
A
uto-
P
ower-
O
ff). It is switched on again if a key or the
rotary switch is operated. A buzzer tone indicates that the device is
switched off automatically. Automatic switch-off can be deactivated
by pressing the „RANGE“ key and by simultaneously switching on the
ZA-TEC ZA 1-3 from the switching position „OFF“.
5.1.10 Temperature coefficient of the measured value: 0.15 x (stated meas
-
uring accuracy)/ °C < 18 °C or > 28 °C, related to the value for the
reference temperature of 23 °C.
5.1.11 The ZA-TEC ZA 1-3 is supplied by means of two 1.5 V micro (AAA)
batteries (IEC 6 LR 03).
5.1.12
If the battery voltage falls below the specified operating voltage of the
ZA-TEC ZA 1-3, a battery symbol
appears on the display
.
5.1.13 The battery life is approx. 250 hours (alkaline battery).
5.1.14 Dimensions of the device:
(L x W x H) = 156 x 74 x 44 mm with suspension fixture
Weight: 320 g with suspension fixture and battery
5.1.15 The enclosed safety measuring leads are explicitly intended for the no-
minal voltage and the nominal curent of the ZA-TEC ZA 1-3.
5.1.16 The ZA-TEC ZA 1-3 can be set up by means of a foldable support or
can be attached by means of the suspension fixture.
5.1.17 The ZA-TEC ZA 1-3 is equipped with a detector as voltage indicator at
its top side to localize earthed AC voltages.
