The HT Instruments HT410 is a 3100 counts handheld digital multimeter with IR (RS232) connectivity.
It is probably a low-cost OEM version of the Rishabh 15S (see Gossen Metrawatt, Metrahit 15S) or a similar model with much worse specs, although the actual accuracy of Matthias' device seems to be better than the specs, according to the calibration certificate (!) that came with it. At least the test cords that come with it are Rishabh brand and cheaper quality than orginal Gossen Metrawatt ones, although they look the same. The same seems to be true for case and sleeve.
The IR connectivity is undocumented, possibly because no IR interface or software is available from the manufacturer. To enable sending data, press the DATA button while powering it on. See here for fitting interfaces.
Hardware
- Battery: 9 V NEDA1604, JIS006P, IEC6F22
- Fuse:
- Current 300 mA: FF 1,6 A/1000V, 6,3x32 mm, 10 kA
- Current 3A, 10A: FF 16 A/1000V, 10x38mm, 30 kA
- TODO.

The column "sigrok result" contains in short form what the driver generates for the resp. data type.
The accuracy specification is incomplete, see manual for exact specs.
