            Measurement Category II: For measuring electrical and electronic devices that are
 CAT. II    directly supplied with a mains voltage via a mains plug. This category also
            includes all lower categories (e.g. CAT I for measuring signal and control
            voltages).
            Measurement category Ill for testing and measuring circuits that are connected
 CAT. Ill
            to the distribution section of low-voltage power supply devices in buildings.

Function Buttons
       This function allows the user to set the magnetization effects to zero
       when measuring DC. It must be performed after each high
       amplitude current measurement.
       With no conductor inserted into the clamp, press and hold the "Z /
       F" key (approx. 3 seconds) until a beep sounds and the ZERO
       symbol appears on the display.
       Press the "Z / F" key to switch the respective secondary function
       between the different measurements for the applications accessible
       via the function switch such as between AC and DC.
                                   7
Press the "MAX/ MIN" button to display the minimum or maximum
values one after the other. Press and hold the button for more than
2 seconds to exit MAX/ MIN mode.
Work light: Press and hold this button for more than 2 seconds to
switch the work light on or off.
                            8
Other Functions
AC voltage measurement with low-pass filter "LPF"
The"LPF" function allows the clamp meter to filter interfering signals of over 60
Hz. These signals can lead to inaccurate measurements. The meter filters
these signals and only measures the voltage signal.
The LowZ voltage measurement must not exceed 600 V. Due to the reduced
impedance, this measurement function is not suitable for continuous
measurement. The measurement duration of 1 minute must be observed.

Operating Instructions                                                        .,1
Automatic shutdown
No operation in 15 minutes, the clamp meter beeps 3 times. Without further
operation, the clamp meter beeps again and switches off automatically.
Press any key to restore the clamp meter to operating status. The symbol
appears on the display.
To deactivate the automatic switch-off, hold down the "Z / F" key for more than 2
                                        11
seconds and switch on the clamp meter at the same time. The symbol
disappears. Restart after switching off the meter, the automatic switch-off can be
restored.
Auto-ranging
The meter automatically selects the measuring range that is best suited for the
measurement performed. The measuring unit and resolution are adjusted at the
same time.
AC Zero Input Behavior of True-rms Meters
Unlike averaging meters, which can accurately measure only pure sinewaves,
True-rms meters accurately measure distorted waveforms. Calculating True-
rms converters require a certain level of input voltage to make a measurement.
This is why ac voltage and current ranges are specified from 5 % of range to
100 % of range. Non-zero digits that are displayed on a True-rms meter when
the test leads are open or are shorted are normal. They do not affect the
specified ac accuracy above 5 % of range.
Connecting Test Leads
Do not test if leads are improperly seated. Results                    INCORRECT
1. Turn the rotary switch to the correct current setting (60A / 600A). "DC"
appears on the display. Press the "Z / F" button, AC is shown on the display.
2. Press the clamp release lever and open the clamp.
3. Grasp the individual current conductor to be measured and close the current
clamp again. Position the conductor in the middle between the two triangular
position symbols on the pliers.
   ► Do not use the current clamp to surround more than one conductor.
  ► If the supply and return conductors (e.g. Land N) are measured, the currents
    will cancel each other out and no measurement will be displayed. The cables of
    household appliances usually contain L and N conductors. A cable separator is
    required to measure with the current clamp.
                                         13
  ► If several supply conductors (e.g. L1 and L2) are measured, the currents add up.
  ► Center the conductor through the current clamp (above the markings)
  ► Hold your fingers behind the tactile barrier.
