MERCURY 1.4. DEFINITION OF MEASUREMENT (OVERVOLTAGE) CATEGORY Standard “IEC/EN61010-1: Safety requirements for electrical equipment for measurement, control and laboratory use, Part 1: General requirements”, defines what measurement category, commonly called overvoltage category, is. § 6.7.4: Measured circuits, reads: (OMISSIS) Circuits are divided into the following measurement categories: · Measurement category IV is for measurements performed at the source of the low-
voltage installation. Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units. · Measurement category III is for measurements performed on installations inside buildings. Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to fixed installation. · Measurement category II is for measurements performed on circuits directly connected to the low-voltage installation. Examples are measurements on household appliances, portable tools and similar equipment. · Measurement category I is for measurements performed on circuits not directly connected to MAINS. Examples are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS-derived circuits. In the latter case, transient stresses are variable; for that reason, the standard requires that the transient withstand capability of the equipment is made known to the user.

2. GENERAL DESCRIPTION
The instrument has the following features:
Multimeter function · DC/ AC / AC+DC TRMS voltage · DC / AC / AC+DC TRMS current · DC / AC / AC+DC TRMS current with clamp transducer · Resistance and Continuity test · Diode test · Capacity · Frequency · Duty Cycle · Temperature with K-type probe · Data Logger function and display of graphs of measured data · Storage of BMP images on external micro SD card
Thermal camera function · Infrared temperature measurement ranging from -20°C to 260°C · 3 measuring cursors (central steady + hot spot + cold spot) · Emissivity of materials which can be selected between 0.01 and 1.00 · Image frequency: 50Hz · 5 selectable color palettes · Automatic detection of hot/cold spots of the image · Storage of BMP images on external micro SD card · IR sensor resolution: 80x80pxl · Bluetooth connection to mobile devices through the APP HTMercury · Built-in laser pointer and illuminator
Each of these functions can be selected by means of the appropriate switch. The instrument is also equipped with function keys (see § 4.2), analogue bargraph and LCD TFT high-contrast color display. The instrument is also equipped with an Auto Power OFF function which automatically switches off the instrument after a certain (programmable) idling time.
2.1. MEASURING AVERAGE VALUES ANDTRMS VALUES Measuring instruments of alternating quantities are divided into two big families: · AVERAGE-VALUE meters: instruments measuring the value of the sole wave at
fundamental frequency (50 or 60 Hz). · TRMS (True Root Mean Square) VALUE meters: instruments measuring the TRMS
value of the quantity being tested. With a perfectly sinusoidal wave, the two families of instruments provide identical results. With distorted waves, instead, the readings shall differ. Average-value meters provide the RMS value of the sole fundamental wave; TRMS meters, instead, provide the RMS value of the whole wave, including harmonics (within the instruments bandwidth). Therefore, by measuring the same quantity with instruments from both families, the values obtained are identical only if the wave is perfectly sinusoidal. In case it is distorted, TRMS meters shall provide higher values than the values read by average-value meters.
