Amprobe ACDC-3400 IND AC/DC CAT IV TRMS Clamp Meter

(8 customer reviews)

  • True-rms sensing increases measurement accuracy in noisy environments
  • Measures AC/DC current up to 1000 A, AC voltage to 1000 V and DC voltage to 750 V, frequency, resistance, and capacitance and duty cycle
  • Peak hold checks transients and motor start currents for spikes
  • Relative zero displays the difference between the actual reading and a stored reference value and may be used with any function or range
  • Audible continuity helps quickly identify opens and shorts
  • Auto and manual ranging for measurement speed and flexibility
  • Data hold holds the reading on the display for further analysis
  • Diode test quickly finds voltage drops
  • Accommodates conductors up to 2″ (51 mm) in diameter
  • Safety rated to CAT IV 600 V and CAT III 1000 V
  • Auto power off conserves battery life
  • Backlight makes it easy to read even in dark conditions
SKU: 3434889 Category:


The Amprobe ACDC-3400 clamp multimeter is CAT IV rated to add an extra level of safety for high voltage, industrial or utility testing applications. It is an AC/DC current clamp meter and a voltage meter all in one.

This clamp-on electrical multimeter includes True RMS sensing for accuracy and dependability and extra large jaws to clamp around conductors up to 2″ (51 mm) in diameter.

  1. Brad79

    Top quality product

    Fast, accurate and simple to use. One of our electricians admitted to dropping the meter off a 12′ step ladder (due the fact that it still functioned properly). Congratulations to your R&D Dept, great quality!

    ✔ Yes, I recommend this product.

  2. cbarnes

    good product

    This meter works great, my only complaint would be that clamp is to big for some of the panels that I work in. Otherwise it is a great meter, simle to use with acurrate readings.

    ✔ Yes, I recommend this product.

  3. bigbadwolfe

    Easy to use.

    I am an electrician at a college. I have to constantly monitor pwer usage. We are in the process of switching all lighting to LED. This amprobe has been a great help in monitoring the amperage or my loads. The larger thinner amprobe clamp makes it easy for me to get this into tight spaces. It is a great product and very reliable.

    ✔ Yes, I recommend this product.

    Easy To Use

    I actually stumbled on to this product by a local 3 electrician and he loan me this meter to test my power lines. It was simple to understand and use. Working as an apprentice for the day with Habitat For Humanities this tool kept me safe. I knew that the line was live and I knew how much juice was coming through it. It kept me safe.

    ✔ Yes, I recommend this product.

  5. keats5

    This product is great for any industrial electrician

    I have been using this meter for a few months now! Great meter for an industrial electrician! A++ Product and well trusted brand!!

    ✔ Yes, I recommend this product.

  6. MAP123

    Accurate and easy to use.

    I love my amprobe amp meter. It is accurate and easy to use.

    ✔ Yes, I recommend this product.

  7. Ralph001

    My #1 meter

    I purchased this meter around 2012. I have been an electrician for 30 years. I purchased this meter to work on everything from basic circuits to control/process circuits and to have a meter that would be the last word. It has done that and has never let me down. I am sending it in for calibration and if need be, I will replace it with the same Amprobe model.

    ✔ Yes, I recommend this product.

  8. dave

    Pro: Sturdy case. 1000 Amp DC and AC. Has calibration feature on the meter. DC and AC voltage measurements are accurate.
    One reasonable price and reliable meter for DC current measurements.
    Con: 600A and 1000A that’s too close. The 600A give a decimal but really doesn’t reliable measure below 1A.
    Peak for in-rush current is on AC only.
