121GW Companion

121GW Companion connects your 121GW multimeter to your iPhone over Bluetooth. - Live: the reading drawn like the meter's display, with its symbols and bargraph; statistics (min, max, mean, standard deviation); derived values (REL, 4-20 mA loop, Pt100 / Pt1000 temperature, limit test); the meter's keys from the phone. - Scope: up to 6000 readings on a scope grid, time base 10 s to 10 min, stop / run and two cursors. - Log: record every reading to a CSV file and share it. - Voice notes: while recording, say what you are measuring; your words are recognised on the iPhone and written into the recording next to the readings. No audio is kept. - Card: list, download and manage the files on the meter's SD card. - Meter: firmware and bootloader updates over Bluetooth, the meter's settings, clock sync and a diagnosis report. Made for the open firmware of the 121GW: github.com/zombu4/121GW-Open-Firmware Free: no account, no ads, no in-app purchases, no data collected. Turn Bluetooth on at the meter with a long press of PEAK.
