the kaiweets backlight automatically activates in the color orange, when U go past 80-100 V. the normal backlight color is white!

[@Edisson.]

That's right

[@mariomionskowski6223]

Indeed.

[@simontay4851]

The AN870 is surprisingly accurate and it uses all the digits. I might buy it.

[@Manf-ft6zk]

Thank you for the very interesting presentation. I really like the Aneng for the design and the price as the accuracy is anyway good enough. As I do not need 20000 counts all the time I use smaller versions from Aneng in more compact cases which fit well between all the things on the desk.

[@Homer19521]

Backlight indicates hi voltage.

[@Chris_Grossman]

it came on as the voltage was raised

[@lightshine6044]

If you put HT118E in diode mode, and let both tips of probes touch each other, does it make a beep sound? Thanks

[@johnwest7993]

I was surprised to see the HT118E was only rated to an altitude of 2,000 meters. Living at the base of the Rockies and the Continental Divide I'd need a meter rated to at least 10,000 feet. I've used multimeters more than once at that altitude. What gives with the 2,000 meters? Cheap capacitors?

[@guateque1718]

The other 20,000 count cheapie is the ut89xe but nobody has reviewed or compared it as far as I know.

[@PeetHobby]

It seam that the red backlight came on when go over 60v(or so) and go off when it dropped below 60v again. Maybe an indication light that you are measuring a high voltage?

[@georgesampson4714]

As both of these meters are about 1/10 the price of the Agilent U1272a in what situations would I need to spend the extra money for the Agilent?

[@IMSAIGuy]

you may never. if you are doing paid work you might want one.

[@TheElectronicDilettante]

I understand the use of gold on pcb applications to help mitigate corrosion. But , as an inferior electrical conductor why is gold used for test probes?

[@IMSAIGuy]

other metals will develop a thin resistive oxide layer

[@nickcaruso]

Why do dmms not use rechargeable batteries? Is it just inertia on the part of manufacturers or is there a technical reason?

[@IMSAIGuy]

search 'rechargeable multimeter' and you will find some

[@rgruenhaus]

I was trying to detect a microwave diode good/bad and it is only showing OL in either direction.

[@roboanalogtom]

At a ~0.15% error for basic DC for 20,000 counts I would honestly send it back and hope for a slightly better unit even if that is spec for the meter. But, I use cheaper meters with more casual measurements so I doubt it would make a difference and at least the error is consistent.

[@ivolol]

Spec is supposed to be 0.08%+5

[@ProdigalPorcupine]

Indeed, I don't see the point of resolution without accuracy! I'd much rather have the Aneng.

[@pglick123]

Try the function key then the light button to change the back light.

[@mr1enrollment]

I have never investigated,... are such meters subject to calibration? Or are they fixed?

[@IMSAIGuy]

They are fixed. I have not seen any manufactures release calibration procedures. Even if they did, it would probably require special software and equipment

[@ivolol]

They are calibrated at the factory. Most have an 8 pin eeprom to store their cal data.

[@ivolol]

That seems to be out of spec on the DCV out of the box 🤔 (0.08%+5) Aneng is barely meeting their's (0.05%+5)

[@mariomionskowski6223]

It is to cold in your Lab for testing the accuracy of a Multimeter, 8,2°C.......

[@yornotelppa]

Discount codes don't work!

[@IMSAIGuy]

That's what I was given. I can ask. buying from amazon or kaiweets.com is different

wow its digital multimeter not analog ones

[@subramanianr7206]

Thanks 👌👍 De VU2RZA
