5. General information
5.1 General information on the current clamp multimeter
5.1.1 The digital display 1 is a 3½-digit LC display with a font size of 14 mm
and a decimal point. The highest numerical value to be displayed is
2000.
5.1.2 The polarity indication 2 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 Measured value storage “HOLD“: Press the “HOLD“ key 4 to store the
measuring result. At the same time, the display shows the “H“ symbol.
Press the key again to switch back to the measuring mode.
5.1.5 The MAX key function 5 automatically determines and stores the
highest measured value. By pressing the key, the following values are
displayed:
“MAX“ shows the highest stored value. The continuous determination of
the MAX value can be stopped or started by pressing the “HOLD“ key
4. Press the “MAX“ key to switch back to normal mode.
5.1.6 Press the 6 V~/ V or Ω/ key to select the secondary function of the
sliding switch position (see indication on the display).
5.1.7 The nominal measuring rate of the TESTFOX CC is 1.5 measurements
per second for the digital display.
5.1.8 The TESTFOX CC can be switched on or off by means of the sliding
switch 7. Switched off: position “OFF“.
5.1.9 The TESTFOX CC is switched off automatically after approx. 10
minutes (APO, Auto-Power-Off). It is switched on again if a key or the
sliding switch is operated. A buzzer tone indicates that the device is
switched off automatically.
5.1.10 Temperature coefcient of the measured value: 0.2 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 CC is supplied by means of two integrated 1.5 V micro
(AAA) batteries (IEC LR 03).
5.1.12 If the battery voltage falls below the specied operating voltage of the
TESTFOX CC, a battery symbol appears on the display.
5.1.13 The battery life is approx. 200 hours for the TESTFOX CC (alkaline
battery).
5.1.14 Dimensions of the TESTFOX CC:
(L x W x H) = 190 x 70 x 38 mm
Weight: 225 g
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 cuurent of the TESTFOX CC.
5.1.16 Largest clamp opening: 30 mm
5.1.17 Largest cable diameter: 27 mm
6. Ambient conditions
- The TESTFOX CC 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,
- Contamination class: 2,
- Protection category: IP 30 (DIN VDE 0470-1 IEC/ EN 60529)
3 – rst index: protection against access to dangerous parts and protection
against solid impurities of a diameter > 2.5 mm
0 – second index: no protection against water,
- Operating temperature and relative air humidity:
For operating temperatures from 0 °C to 30 °C: relative air humidity less than
80 %,
For operating temperatures from 31 °C to 40 °C: relative air humidity less than
75 %,
For operating temperatures from 41 °C to 50 °C: relative air humidity less than
45 %,
- Storage temperature: The TESTFOX CC can be stored at temperatures
between - 20 °C and + 60 °C (air humidity of 0 to 80 %). During storage, the
battery should be removed.
7. Electricalspecications
Note: The measuring accuracy is specied as the sum of:
- a relative part of the measured value and
- a number of digits (i.e. counting Stepps of the last digit).
