RMS VOLTMETER SPECIFICATION
















   
Power supply:
  120V/240V ± 6%    50/60Hz.      
         
Input signal: 
Maximum: 7 volts rms, 10 volts peak.      
         
Frequency range: 
Meter incorporates low and high frequency filtering 10 Hz to10K Hz.          
               
Meter ranges:
  10mV, 30mV, 100mV, 300mV, 1V, 3V, 10V  FSD.      
             
Peak Measurement:
 
Using precision rectification indicates positive and negative   peak signal values. Maximum peak signal 10V.Captures the maximum of either positive or negative signal  peaks. Maximum peak signal 10V.
 
         
Peak hold facility:
 
Switch selectable for peak signal measurement Single time constant for RMS measurements to provide stable reading over frequency range 10Hz to10kHz.
       
Damping:
   

No damping applied to Peak hold measurements to ensure accurate capture of short duration  signals.

 
       
Signal processing circuits and power supplies use analogue technology to minimise RFI generation.
Circuit technology:
 
Overload indication
    Range selected indicator changes from green to red when signal overload occurs.  
           
 
Input signal protection:
    Internal circuits fully protected against accidental application of excessive input signals. Dynamic  signal clamp to protect front panel meter from overload range.  
           
 
Compliance:
The unit fully complies with applicable European Directives as follows:- Low Voltage Directive 78/23/EEC.
