DatasheetResistance measuring:
- precise indication of resistance between 10 mΩ bis 2 MΩ
- universally applicable due to large measuring range and automatic range selection
- energy-saving circuit for high measuring current 0.2 A for Lo-ohm range up to 10 Ω
- large display with backlight
- acoustic warning signal for resistances less than 2 Ω
- fast compensation of measuring line per keypress
- automatic pole change and storage of measurement results (+/- valules)
Safety:
- clear LED indicator for dangerous voltage
- voltage value on the LCD and warning acoustic signal
- protection circuit against external voltages up to 400 V.
- integrated fuse for overvoltages over 400 V
More functions:
- ex-proof version
- varied accessories
- easy handling and compact design
- robust casing
- IP 65 – waterproof
