#144254 - Proper reading? Responding to: ???'s previous message |
Jprao said:
I want to measure a voltage ranging from 500V to 6 KV. I am using resistor divider to get the voltages from 0.5V to 6 V. This voltage is to be given to DPM for display. But the reading is not coming properly Can you explain just how "the reading is not coming properly"? Are you having trouble with offset, range, non-linearity, or what? What kind of resistors are you using for your divider? Have you considered their voltage coefficient? Rob. |

| Thanks to all | 01/01/70 00:00 | |
| That's all very well | 01/01/70 00:00 | |
| Yes, Jprao, please answer our questions! | 01/01/70 00:00 | |
| DIffierent Divider Perhaps | 01/01/70 00:00 | |
| DPM? | 01/01/70 00:00 | |
| DPM is a widely used term... | 01/01/70 00:00 | |
| many DPMs use ICL7106 | 01/01/70 00:00 | |
Yes, evolves into a heart-stopping thread... | 01/01/70 00:00 |
