LM336-5.0: Question on fast sampling measurement method of current

Dear person in charge

Hello,

Thank you for your continued support.
My name is Kengo Suzuki from Daifuku.

Case Number:  CS1162154

I would like to ask your company again about the measurement method: 5V Reference Diode (aka Zener Diode): LM336MX-5.0/NOPB with HP 34401A digital multimeter, the maximum measurement speed is 1000 times/sec (= 1msec sampling).

What is the basis for your company's measurement of the 5V reference diode: LM336MX-5.0/NOPB using this instrument with a maximum measurement speed of 1000 times/sec (=1msec sampling)?

The board on which our LM336MX-5.0/NOPB is mounted is used for a current input/output circuit that samples at 0.1msec (=100μsec).

I would like to measure the current with 0.01msec (=10μsec) sampling, but even the successor to the measuring device you introduced, the 34461A (Keysight Technology), can only measure up to 1000 times/sec (=1msec sampling).

I am sorry to trouble your company and would appreciate it if you could enlighten me.

Best,

Kengo

    Hello Kengo,

    I assume you are referencing your previous question. The HP 34401A digital multimeter is only an example of a high precision multimeter and is not a standard. You will need a different meter that is capable of 0.1msec or greater sampling for your measurement.

    Best,
