Review: DROK Digital Multimeter - Great product! - DROK Digital Multimeter - Great product! I have a RELIANCE transfer switch with two analog Amp meter. I connect this transfer switch to my home electrical panel and to transfer 6 specific circuits to me generator when the power goes out. One of the Reliance Amp meter was not working well so I ourchased these two DROK Multimeter to replace them. The wiring was clear enough (both on the back of the unit and on the notice). there was some comments on previous reviews on the length of the wires included with the package. I found them long enough if you intend to set your Multimeter next to the transfer switch box. Set up took less than 20 min and the meters are working perfectly - showing both voltage and amps. I would recommend this product to anyone who would like to have a measure of the amp and voltage coming out of your generator.
Review: DROK multimeter - Amazing product, cheap and reliable. The energy counter does not reset to zero after an outage. It simply resumes working. I am now waiting for the outdoor version. This only should be installed indoors.

## Features

- It is a compact, lightweight and functional multi-meter, with large-screen LCD display, can display voltage, current, active power and energy at the same time. It does not control or effect the load in any way.
- Voltage test range: AC 80~260V; Current test range: 0~100A; Power test range: 0~22KW; Energy test range: 0~9999kWh.
- Display has great visibility, very bright and clear; the blue backlight can be turned on/off by the front accessible recessed switch located on the right side bezel.
- Multifunctional: the accumulated energy can be reset by button; Store data when power off; Power alarm threshold preset function; Overload alarm function (over power alarm threshold, backlight and power will flash to alarm).
- Perfect to work with a generator or solar panel setup, also great to monitor accumulated energy usage on devices that cycle on and off(refrigerator, dehumidifier, washing machine, wall a/c unit) and the phantom load(cable modem, router, DVR).

## Questions & Answers

**Q: I would like to read wattage on a 240vac circuit, which in usa is two 120vac legs that are 180 degrees out of phase.  Is there any easy way with 1 CT**
A: This may help you:  In order to PROPERLY read current on split phase systems like a typical house, You need THREE Current transformers and meters (NOT 3-PHASE!).
1 on L1, 1 on L2, and 1 on NEUTRAL (ALL of them)  The neutral leg will show all 120v current on BOTH busses.  The other two will allow you to separate viewed currents of the 240 from the 120 devices:

IE: meters show:  L1 - 10A  L2 - 12A , Neutral - 2 A.  THAT would mean your 240v devices are pulling 10 A and The devices on L2 to neutral (120v) is pulling 2A.  Another example:  L1 - 12A, L2 - 13A  Neutral - 5A  Tis would be: all 240 devices pulling 10A   120v Bus L1 is pulling 2A, and 120v Bus L2 is pulling 3A.  FInal Example:  L1-13A, L2-12A, Neutral - 25A.  This would show NO 240 devices drawing power, 120v L1 Bus draws 13A , 120v L2 Bus draws 12A.  This may be a little confusing at first, but work it out in your head, you will see.

**Q: Can this meter run for long periods of time when connected to a 7000 watt generator?**
A: I have a dozen of these in various electrical loads in my plant, they run 24x7 and are over 1 year old, no problems.

**Q: Does this include wiring requirments. the q and a make it seem as this is just the lcd for an remote unit.**
A: There is a simple picture on the box. Two wires for volts, for 120 on to power, one to neuteral. For 240 both to power. The inductor has to have a power wire run through the center. I had to extend the leads on the inductor on all 5 i have used. I hope this  helps.

**Q: I want to measure the power of a pool heat pump using 240 ac in us measurements. do i take both legs (using 2 meters) and combine the readings?**
A: If you don't mind doing the math you can use 1 meter and measure 1 side of the 240v (120v) . Example: If it draws 35 amps on the leg (phase) your reading it will draw 35 amps on the other. Same formula, if it shows 4.2 KW on the leg (phase) your reading then it will draw 4.2KW on the other. This would make the total KW of the heater 8.4 KW or 8400 watts. This meter will show you volts, amps and KW

### ⭐⭐⭐⭐ Good prduct at a reasonable price
*by O***T on May 19, 2016*

I bought this to monitor the load on a 6kW Onan diesel generator I use to recharge my home battery backup system in emergencies. Inexpensive, but works just fine. I used CAT5 cable for the connections, doubling up the 8 wires to make 4 pairs. As others have commented, the leads on the CT transformer are short, but in many applications they'd likely need to be lengthened anyway, so I don't know what factory length might be considered useful. Note: If you are also buying a box to mount this in, I'd recommend a metal one (or one with a metal front panel like this one: Electronics Enclosure Plastic Project Box 5.25" x 3.25" x 1.562" ) as the tabs that secure the unit don't allow quite enough clearance for the thicker wall of the plastic box I had on hand. However, I was able to shave a tiny bit off the tabs to accomodate this.
