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 denition 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
approx. 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 TESTFOX M/ M-1 is 2 measurements
per second for the digital display.
5.1.8 The TESTFOX M/ M-1 can be switched on or off by means of the rotary
switch 8. Switched off: position „OFF“.
5.1.9 The TESTFOX M/ M-1 switches off automatically after approx. 10
minutes (APO, Auto-Power-Off). 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
TESTFOX M/ M-1 from the switching position „OFF“.
5.1.10 Temperature coefcient of the measured value: 0.15 x (stated measuring
accuracy)/ °C < 18 °C or > 28 °C, related to the value for the reference
temperature of 23 °C.
5.1.11 The TESTFOX M/ M-1 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 specied operating voltage of the
TESTFOX M/ M-1, 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 xture
Weight: 320 g with suspension xture and battery
5.1.15 The safety measuring lines are designed in 4 mm plug-in technology.
The enclosed safety measuring lines are explicitly intended for the nominal
voltage and the nominal curent of the TESTFOX M/ M-1.
5.1.16 The TESTFOX M/ M-1 can be set up by means of a foldable support or
can be attached by means of the suspension xture.
5.1.17 The TESTFOX M/ M-1 is equipped with a detector as voltage indicator
at its top side to localize earthed AC voltages.
6. Ambient conditions
- The TESTFOX M/ M-1 is intended for measurements under dry ambient
conditions,
- Maximum barometric height for measurements: 2000 m,
- Overvoltage category / installation category: IEC 60664-1/ IEC 61010-1 →
600 V category III; 1000 V category II,
- Contamination class: 2,
- Protection category: IP 30 DIN VDE 0470-1 IEC/EN 60529
IP 30 means: Protection against access to dangerous parts and protection
against solid impurities of a diameter > 2.5 mm, (3 – rst index).
No protection against water, (0 – second index).
