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

the kaiweets backlight automatically activates in the color orange, when U go past 80-100 V. the normal backlight color is white!
That's right
Indeed.
If you put HT118E in diode mode, and let both tips of probes touch each other, does it make a beep sound? Thanks
The AN870 is surprisingly accurate and it uses all the digits. I might buy it.

Backlight indicates hi voltage.
it came on as the voltage was raised

The other 20,000 count cheapie is the ut89xe but nobody has reviewed or compared it as far as I know.
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?
you may never. if you are doing paid work you might want one.

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

Why do dmms not use rechargeable batteries? Is it just inertia on the part of manufacturers or is there a technical reason?
search 'rechargeable multimeter' and you will find some

other metals will develop a thin resistive oxide layer
I have never investigated,... are such meters subject to calibration? Or are they fixed?
They are fixed. I have not seen any manufactures release calibration procedures. Even if they did, it would probably require special software and equipment
They are calibrated at the factory. Most have an 8 pin eeprom to store their cal data.
Try the function key then the light button to change the back light.

Spec is supposed to be 0.08%+5
Indeed, I don't see the point of resolution without accuracy! I'd much rather have the Aneng.
Discount codes don't work!
That's what I was given. I can ask. buying from amazon or kaiweets.com is different

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)
It is to cold in your Lab for testing the accuracy of a Multimeter, 8,2°C.......
wow its digital multimeter not analog ones
Thanks 👌👍
