Same answer as in your other thread. AFIK the MS5308 uses the same chipset as the DE-5000. It has 0.5 Vrms excitation voltage or .707 peak. lower but I still dont think considered in circuit levels. I don't see a user cal button/feature on the MS5308 manual . This is a big deal if you intend to use tweezers or external clips. Edit: The cal button is on the top of the case. The DE-5000 manual shows how it works. |

You'll find b*gg*r all in the Mastech manual! it's a wsate of paper. Yes, get hold of the DE-500 manual - it all applies to the Mastech (which does have a calibrate button, as you point out). Lots of talk of probe measuring voltages, so here are some actual figures (across a 1uF mylar cap) At 100 Hz - 1.9V pk-pk AC waveform about 0V At 1KHz - 1.4V pk-pk AC At 10KHz 250mV Pk-Pk At 100KHz 28mV Pk-Pk And across a "typical" supply cap of 470uF (standard, not particularly high quality low ESR) at 100 Hz - 55 mV Pk-Pk on a tiny DC offset at 1KHz - ~15mV Pk-Pk higher frequencies - unmeasurable! So in practice, in-circuit measurements are often way below transistor junction turn-on voltages. |

ok.. more than 1KHz test frequency in circuit measurement is not possible?? m i right??? which one is cheap and better ESR meter please suggest |
| T4P:
NO! It's good for in circuit measurement. |
