Portable Three-Phase Energy Standard
PEWM-3C
The three-phase energy standard PEWM-3C is used for quick on-site tests of all types of electricity meters – for active, reactive or apparent energy, two-, three- or four-wire connection. Three voltages and three currents are measured at the same time. The current can be measured either via direct connection up to 10A (class 0.1), or with three current clamps (CC) to 120A, 150A or 1000A (class 0.2).

Standard Digital Multimeter - Auto Ranging
MM39
The MM39 is an auto-ranging multimeter with a large rotary switch for easy selection of the required test, even when wearing gloves. There are two test buttons, one to lock the range and the other to hold the results which are displayed on a 3½ digit LCD screen.
The main test functions are AC voltage and DC voltage and current and resistance. The MM39 measures both AC and DC voltage between 0.1mV to 600V and AC and DC current between 10mA to 10A. There is a diode test and an audible continuity test which sounds at less than 25Ω.
