5. General data
5.1 General data on multimeter
5.1.1
The digital display is designed as a 3 3/4 digit liquid-crystal indicator with 13
mm digit height and decimal point. The highest value displayed is 3999.
5.1.2 The polarity indication
functions automatically. Contrary to the
measurement-wire definition, only one pole is indicated as “-”.
5.1.3 The range overload will be displayed with "OL" or "-OL" and sometimes
with an acoustic signal.
Attention: no display or warning by complete overload.
5.1.4 The nominal measuring rate of the digital display of the TESTFOX CC–1
is approx. 2 measurements per second.
5.1.5 The TESTFOX CC–1 switches off automatically after approx. 30 minutes.
It can only be switched on again by means of the switch. The buzzer
sounds to signal that the unit has switched off automatically.
5.1.6 Temperature coefficient of measurement value for voltage and
resistance measurements: 0.15 x (stated measurement accuracy)
°C < 18 °C or > 28 °C with reference to the value at the reference
temperature of 23 °C.
5.1.7 Temperature coefficient of measurement value for current measurements:
0.2 x (stated measurement accuracy) °C < 20 °C or > 26 °C with
reference to the value at the reference temperature of 23 °C.
5.1.8 The TESTFOX CC–1 is supplied by 2 1.5 V batteries (IEC LR03/
”Micro”).
5.1.9 When the battery voltage drops under the intended operating voltage of
the TESTFOX CC–1, a battery symbol appears in the display.
5.1.10 The service life of the battery is approx. 60 hours (alkali battery).
5.1.11 Dimensions of unit (length x width x height) = 192 x 66 x 27 mm.
Weight of unit: 205 g
5.1.12 The safety measuring wire and measurement tips are of the 4 mm/ 2
mm plug-in type. The safety measuring wires and measurement tips
supplied are specially suited to the rated voltage of the TESTFOX CC–1.
The measuring tips can be protected by caps.
5.1.13 Widest prong opening: 25 mm
5.1.14 Largest wire diameter: 22 mm
6. Ambient conditions
- The TESTFOX CC–1 is designed only for measuring in dry surroundings.
- Maximum barometric height during measurement: 2000 m
- Overvoltage category / set-up category: IEC 664/ IEC 1010 600 V category II
(300 V category III).
- Degree of contamination: 2
- Protection Class: 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 - first index). No
protection against water, (0 - second index).
- Operating temperature and relative humidity for voltage and resistance
measurements:
At operating temperature of 0 °C to 30 °C: relative humidity under 80%
At operating temperature of 30 °C to 40 °C: relative humidity under 75%
At operating temperature of 40 °C to 50 °C: relative humidity under 45%
- Operating temperature and relative humidity for current measurements:
At operating temperature of 0 °C to 30 °C: relative humidity under 80%
At operating temperature of 30 °C to 40 °C: relative humidity under 75%
- The TESTFOX CC–1 can be stored at temperatures from - 20 °C to + 60
°C. The batteries must be removed from the unit.
7. Electrical data
Note: The measurement accuracy is stated as the sum of
- a relative proportion of the measurement value and
- a number of digits (i.e. numerical steps of the last place).
This measurement accuracy applies for a temperature of 23 °C ± 5 °C (23 °C ± 3 °C
for current measurement) and a maximum relative humidity of 80%.
