| [Poll] Benchtop DMM Acceptable Power On Time? |
| (1/7) > >> |
| Leeima:
I just upgraded to the Keysight 34465A and noticed that it took an age to turn on. I had been using an Agilent 34401A which powers on from fully off (mains disconnect power button) to being able to measure a DC voltage in under 3 seconds. This is about the time it takes me to adjust my chair. The Keysight 34465A takes a whopping 25 seconds FROM STANDBY! The unit isn't even fully powered off. This just leaves me twiddling my thumbs waiting for the unit to turn on when all I might need to do is check a resistor. With the 34401A I could walk to my bench, perform the measurement and be back to my desk halfway through typing an email before the 34465A has even turned on. I know that for any meaningful measurement you should allow your test equipment time to stabilise its internal temperature; but there are times you just need a quick and dirty measurement, so for those general purpose times what is your opinion? |

My first DMM was the 289 and at the time the around 5s from pressing the button until being ready to measure was acceptable for my needs, compared with that the equipment in question can do. At the time I didn't know better, back in 2007. Nowardays after some more years and now also owning the 87V I must say I love the almost instant on of it, to the point that I think the 189 would had been a better choice back at the day. Still I think that anything close to 5sec is the right amount. |
| Leeima:
I hadn't considered handheld multimeters. A fast on time is even more important with them, since you're always switching them off to conserve the battery. The 189 is definitely faster than the 87IV (I don't have either of mine to hand to check) |
| David Hess:
A handheld meter should be ready immediately. A bench multimeter can take time because it is going to be left on all day anyway. |
| Leeima:
I just decided to measure the power on time for all the multimeters my firm has laying around. Unfortunately these are all older models (read software light) so I don't have any comparison to other current model top brand meters. |
