Compact light instruments, are ideal for measurement and record of signals, are intended for the measurement and the writing into the memory of the values of current ACE and the currents leakages beside different time intervals with the aid of the current-measuring tongs (option).
Model 3636-20 is intended for measurement and record only of values of current ACE.
Model 3638-20 is intended for measurement and record only of values of the leakage currents.

• Large volume of internal storage, to 32000 elements of the data
• Possibility of connection based on PK on the means USB or RS-232 (option) and graphing regarding the obtained values.
• Possibility of the automatic writing of the measured values into the memory of instrument during the long time, through the established time intervals
• Data remain before the memory of instrument, even when battery is discharged
• The presence of the function of power of save (savings of energy), function makes it possible to increase the duration of the record
