if you really want to pi** on my battery and put me in a bad mood...here a good way top do it.
sell me an AC voltage /current data logger (major tech MT 250) for R1599.00
"tell me the unit is a true RMS meter" (http://www.major-tech.com/Website/Pr...ProductID=3134) ...but when i use in conjunction with other true RMS meter and find the reading vary...the real true RMS meters (2 different meters) indicates a voltage of 214 volts... the MT 250 indicates 187 volts.
then carry out a data log at a customer and find the reading is out even on a normal supply by 3-6 volts
when i return the unit and request the meter is checked...get told that i have to pay in R1300 to have it calibrated because major tech cannot carryout the calibration for what ever reason.
i do realise you get what you pay for...but dont then say the unit is something it is not...this unit cannot read distorted sinewaves accurately...only pure sine waves and even that is not accurate.
