DESCRIPTION Voltmeter PCE-ITM 20 The isolation multimeter is a combined multimeter and insulation tester / Test voltage up to 1000 V / Large LCD display / Temperature measurement / Frequency measurement / Internal memory / CAT IV 600 V / IP67 / Wireless USB This voltmeter combines a versatile multimeter with an insulation tester. In addition to the usual measured quantities such as voltage, current and resistance, this voltmeter is also equipped with a frequency and capacitance measurement. A thermocouple included in the delivery can also be used to measure the temperature. Automatic range selection (Autorange) allows fast and safe operation with the voltmeter, while the large backlit LCD display ensures good readability. The highlight of this voltmeter is the integrated insulation tester. With test voltages of up to 1000 V, insulation resistances of up to 5000 MΩ (5 GΩ) are measured. Likewise, the voltmeter can directly measure the PI and DAR value. Thus, it is quickly possible to make a statement about the insulation value of the DUT with the help of the voltmeter. In addition, this voltmeter has an internal memory. This gives you the opportunity to recall the stored measured values for subsequent analysis in the display and to transfer the measured values via the wireless USB interface from the voltmeter to a PC.
