Measurement Category
Measurement Category
This instrument can make measurements in Measurement Category I.
WARNING
This instrument can only be used for measurements within its specified measurement categories.
Measurement Category Definitions
· 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. Thus, you must know the transient withstand capability of the equipment.
· Measurement category II is for measurements performed on circuits directly connected to low voltage installation. Examples are measurements on household appliances, portable tools and similar equipment.
· Measurement category III is for measurements performed in the building installation. Examples are measurements on distribution boards, circuit- breakers, wiring (including cables, bus-bars, junction boxes, switches and socket-outlets) in the fixed installation, and equipment for industrial use and some other

DG800 Pro Quick Guide 2

Safety Requirement

1.4 1.5

equipment. For example, stationary motors with permanent connection to a fixed installation. · Measurement category IV is for measurements performed at the source of a low-voltage installation. Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units.
Ventilation Requirement
This instrument uses a fan to force cooling. Please make sure that the air inlet and outlet areas are free from obstructions and have free air. When using the instrument in a bench-top or rack setting, provide at least 10 cm clearance beside, above and behind the instrument for adequate ventilation.
CAUTION Inadequate ventilation may cause an increase of temperature in the instrument, which would cause damage to the instrument. So please keep the instrument well ventilated and inspect the air outlet and the fan regularly.
Working Environment
Temperature Operating: 0 to +40 Non-operating: -20 to +60 Humidity
· Operating: 0 to +40: 80% RH (without condensation)
· Non-operating: -20 to +40: 90% RH (without condensation) Below +60: 80% RH (without condensation)
WARNING To avoid short circuit inside the instrument or electric shock, never operate the instrument in a humid environment.
Altitude
· Operating: below 3 km
· Non-operating: below 12 km

Installation (Overvoltage) Category
This product is powered by mains conforming to installation (overvoltage) category II.
WARNING Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the product. Otherwise, the operator might be exposed to the danger of an electric shock.
Installation (Overvoltage) Category Definitions
Installation (overvoltage) category I refers to signal level which is applicable to equipment measurement terminals connected to the source circuit. Among these terminals, precautions are done to limit the transient voltage to a low level. Installation (overvoltage) category II refers to the local power distribution level which is applicable to equipment connected to the AC line (AC power).
Pollution Degree
Pollution Degree 2
Pollution Degree Definition
· Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs. The pollution has no effect. For example, a clean room or air- conditioned office environment.
· Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary conductivity caused by condensation is to be expected. For example, indoor environment.
· Pollution Degree 3: Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs. For example, sheltered outdoor environment.
· Pollution Degree 4: The pollution generates persistent conductivity caused by conductive dust, rain, or snow. For example, outdoor areas.
