DIGITAL DATA LOGGER MULTIMETERS DMK 40 TYPES
   
The DMK 40 multimeter comprises excellent features, that include a very powerful and easy-to-use data logger. Critical waveform conditions, such as voltage and currents with high harmonic content and variable frequency, do not influence the DMK 40 high-accuracy multimeter readouts because of rigorous design in addition to use of the latest generation of microprocessors. The measurements available are more than 247.
Some displayed parameters are the following: 
Voltage:
- Phase, line and system voltage values 
   
Current:
- Phase current values
 
Power: 
- Phase and total active, reactive and apparent power
   values
   
Energy: 
- Active (import and export) and reactive (inductive-capacitive) energy 
  
P.F.: 
- Phase power factor 
  
Cosphi:
- Displacement phase of the harmonic fundamental
  
Frequency:
- Frequency value of the monitored voltage
  
Harmonics:
- Readings of harmonic content including total, residual, of each harmonic order up to the 22° and of each of 
  the three phases, both for voltage and current values
  
High and Low
- -Maximum and minimum instant readings of phase voltage and current as well as SW (import-export), 
  SVar (import-export) and SVA power values
 
Max:
- Maximum readings of current and total active power, sampled according to a programmable period of time
  
Averaging:
- Function to limit repetitive voltage and current variations to obtain stable viewing
  
The data logger is provided with: 2Mbytes of data memory, RTC (Real Time Clock) with back-up lithium battery and a communication port for PC link. Every single data is stored with time and date, according to the data logger setting. A very user-friendly software provides for data logger and RTC settings, data downloading in an ACCESS, EXCEL or TEXT format file and data viewing in graphic form.
