The Gossen Metrawatt Metrahit 27I is a 3100/31000 counts 600 V CAT II handheld digital multimeter with bidirectional IR (RS232/USB) connectivity. It supports milliohm and insulation (megaohm) measurements and has data logging capabilities.
There are two versions of this device, an older one with yellow rotary switch and a newer one with red rotary switch. They also have different power supply connectors.
Hardware
- Power supply:
- Battery: 3x 1,2 V NiMH rechargeable batteries
- External power supply NA HIT 27 (Art. Z218J) by Gossen Metrawatt, 5V, 600 mA (newer version)
- Fuse:
- FF (UR) 1,6 A/1000 V AC/DC (10 kA) 6,3 mm x 32 mm
