Features:

DE-5050/5050R measures insulation resistance, low resistance, and AC/DC voltage.
●Build in back light LCD, convenient for dark places and night work.
●Memory function: Short press STORE key for data saving, max 100 sets.
And long press RECALL key to recall.
●Data saved with measuring time /date information.
●Auto power off when the instrument is left on for 10 minutes without operating.
●Voltage measurement with AC/DC auto detection.
When main display AC voltage is >10V, the sub display shows the frequency value simultaneously.
● Insulation resistance measurement
．Auto discharge function: Automatic discharge after measurement.
．COMPARE function : LCD back light indicates whether a measured value is less (red light ) than / or higher (green light) than the reference value.
．When the insulation resistance measurement starts, the LCD will 　display date, cycle and time of the measurement.
．DAR/PI measurement function
Automatically calculated and displays DAR (Dielectric Absorption Ratio) and PI (Polarization Index) value during the insulation resistance measurement.
．After measuring with MEAS , the voltage will indicate on the sub display of LCD simultaneously.
● 0ΩADJ adjustment
In low resistance measurement, short circle the tips of test leads and press the 0ΩADJ key to cancel the resistance of the test leads.
