Q1074A (above left) - now with 2 year warranty!
The Micron Q-1074A or Digitek DT-9604* or TekPower TP-9605* with its 6000 count auto-ranging display, provides the most accurate measurements of any 4 digit DMM I've seen.# With self-calibration AND the best resolution... 0.01mV or 10uV (ideal for measuring current shunts with 1mV/A output). It also logs data to your PC thru any USB port. Use the supplied Windows program or write your own... example programs available in VisualBASIC and Excel using VBA (Visual Basic for Applications). Now works in Excel 2003, 2010, 2016 (32 bit versions). Our example program captures data and inserts it directly into Excel in real time! Up to 2 times per second! This DMM also features a CAT III 600V rating, up to 60M ohm resistance testing, up to 100,000uF capacitance testing, TRUE AC measurement to 1KHz, diode testing up to 3V (LEDs can be tested), cool blue back-light, temperature measurement in C or F (with a resolution of 0.1) and minimum and maximum recordings of most measurements. Comes with operation manual, 9V battery, test leads, K type thermocouple probe, optically isolated USB lead, PC software and a 1 year warranty. Operates for over 1 week in datalogging mode (3 weeks with lithium battery). For documentation on the USB/RS232 communications protocol - click here. For an example program in QBASIC - click here. *equivalent units with different brand-names! #The fluke 179 has better specs BUT costs over $500!!! To illustrate how accurate the meter is, we set two units side-by-side, auto-calibrated them and connected them to the same power supply and found that the voltage measurement followed each other exactly with only 1 count variation at most!***

QM1571 (above centre) - with lifetime warranty!
The Digitech QM-1571 operates wirelessly (up to 3m) to log data to your PC thru any USB port. Use the supplied Windows program or write your own... example programs available in VisualBASIC and Excel using VBA (Visual Basic for Applications). Now works in Excel 2003, 2010, 2016 (32 bit versions). Our example program captures data and inserts it directly into Excel in real time! Up to 3 times per second! This DMM features 4000 count auto-ranging display, rugged IP67 weather-proof design (it floats on water), CAT III 1000V and CAT IV 600V, non-contact voltage detection* and TRUE-RMS measurement and temperature measurements with the ability to display in C or F. The display resolution is 0.1 degrees.

DPM3232 and DPM3221 (above right)
The Manson Digital DC Power Meters or "Watt meters" come in two versions. The DPM-3232 measures 0-60V DC and 0-20A (60A peak) and is inserted directly between the source and load. The DPM-3221 measures 0-60V DC and 0-50A, 0-100A or 0-200A (user selectable) with an external 50mV current shunt - DPA3016 or QP range. These units are designed to monitor the Voltage and Current output of a DC power source (power supply, charger, battery, solar panel etc.) and records and displays Voltage (V), Amps (A) as well as calculating and displaying; Wattage (W), Watt-hours (Wh), Amp-hours (Ah), minimum Volts (Vm), peak Volts (Vp), minimum Amps (Am) and peak Amps (Ap). The DPM3232 is similar to other Power Meters such as the "Watt's Up" Meter which Radio Control enthusiasts rave about - click here. The advantage of the DPM unit is that it logs the Voltage and Current continuously, at 3 seconds to 3 minute intervals, throughout a model's operation (e.g. a drone's flight) and this data can then be uploaded to a computer. This allows detailed analysis of the performance of the battery and motors and aids fault finding! To upload the data from the DPM, the Data Adapter DPA3051 is required. PC software is provided with the DPA3051 - click here.

Customer comments:'I received the package on October 1st, only 4 days in transit! The meters work great. Thank you very much.' Mack M. USA 'What do they feed those Qantas pilots on? The package arrived Monday! That's as quick as if I ordered something from Maplin - and they're in Essex. Thanks and best regards' Iain Rankin, England.

*** to provide another example why this meter is SO GOOD, one customer complained that it was not very accurate in measuring resistance values below 1 ohm. I suggested that he should be using the "resistance" mode and not the "continuity test" mode and that he should short-circuit the leads and press "Rel" (relative) before trying to measure such a small resistance. In addition I explained that the accuracy of resistance measurements was very limited below 1 ohm because of the resolution being 0.1 ohm +/- 2 counts! I also suggested that there are better methods for measuring such low resistance (e.g. the bridge method) HOWEVER I did start experimenting with resistance values between 1 and 10 ohm and noticed that the Q1074A was more accurate than any other meter that I had... why? It's due to the measuring technique used on the Q1074A... it applies a small positive voltage and alternatively a small negative voltage and, I assume, averages the readings! Most other meters simply apply a positive voltage... just like the continuity test used on the Q1074A meter. If your DMM relies on simply applying a fixed positive DC current and then measuring the DC voltage drop then inaccuracies can occur if the resistor itself generates a voltage! How can this occur? Remember two dissimilar metals can produce a voltage (this is how the thermocouple works), so I decided to try connecting the thermocouple and measure the resistance... guess what? On the Q1074A continuity test and on other meter's resistance test, I found the resistance would increase or decease (depending on the polarity) when the thermocouple was heated (e.g. stick your fingers on the probe) BUT when the Q1074A resistance test was used, the reading REMAINED CONSTANT !!!

The QM1571 datalogging DMM operates wirelessly (up to 3m) on the same frequency, multiple units can NOT be used within close proximity to each other. Multiple DMMs can only be used provided that they are separated by 10+ metres. Details are provided of using different COM ports, when you purchase the DMM-SW CDROM! NOTE: The wired data logging DMM have no restriction, multiple units can be used and connected to one computer. e.g. measure DC voltage and current and calculate power! i.e P=VI.

The QM1571 meter oozes quality inside and out - click here. It is so indestructable that we offer a "lifetime warranty". It is similar to other meters costing much more... but the QM1571 includes wireless data collection and a non-contact voltage detector! "The QM1571 is a comprehensive low cost multimeter, for the money its functionality is fantastic, with everything you would expect with good AC & DC ranges, Frequency and Capacitance measurements, complete with Temperature Probe and Case. Exceptional value for money. Why buy a Fluke?"

* place the top of the QM1571 DMM near AC wiring and a red LED will illuminate. Switch to 400mV DC and select Hertz and display the AC frequency without any physical contact! Note, when collecting data always insert a new battery... a good quality 9V alkaline battery will last 3 days continuously (with wireless operation) and up to 1 week with a lithium battery! Imagine? Now you can monitor data, such as battery voltage, remotely whilst your mobile robot wanders around! Or use the QM1571 in a hazardous environment whilst you collect data direct on your PC. Multiple meters can even be connected to a PC provided they are kept a sufficient distance apart so as not to interfere with each other.

Postscript: The graph below shows how simple it is to plot data obtained by the meters. The temperature probe was plunged into a beaker of ice cold water. The text file, with 100 data samples, was then loaded into an Excel spreadsheet and graphically presented. The graph below was produced by a year 7 student!
