  Safety Symbols on the Product:

1.3 Input Terminal Protection Limits
Protection Limits are defined for the input terminals:
Main Input (HI and LO) Terminals
The HI and LO input terminals are used for voltage, resistance, capacitance, continuity, frequency (period), and diode test measurements. The following two Protection Limits are defined for these terminals:

1. HI to LO Protection Limit: 1000 VDC or 750 VAC, which is also the maximum voltage measurement. This limit can also be expressed as 1000 Vpk maximum.
2. LO to Ground Protection Limit. The LO input terminal can safely “float” a maximum of 500 Vpk relative to the ground.

The protection limit for HI terminal is a maximum of 1000 Vpk relative to the ground.
Therefore, the sum of the “float” voltage and the measured voltage cannot exceed 1000 Vpk.
Sense (HI Sense and LO Sense) Terminal
HI Sense and LO Sense terminals are used only for four-wire resistance measurements. The following two Protection Limits are defined for these terminals:

1. HI Sense to LO Sense Protection Limit. HI Sense to LO Sense Protection Limit: 200Vpk.
2. LO Sense to LO Protection Limit. LO Sense to LO Protection Limit: 2 Vpk.

Current Input (I) Terminal
The I and LO terminals are used for current measurements. The I terminal has a protection limit of 10 A(DM858)/3 A(DM858E) maximum current flowing through the terminal by the front-panel current input fuse.
CAUTION
The current input terminal will be at approximately the same voltage as the LO terminal unless the current input fuse is blown. To maintain protection, replace this fuse only with a fuse of the specified type and rating.
1.4 IEC Measurement Category II
To protect against the danger of electric shock, DM858/DM858E Digital Multimeter provides overvoltage protection for line-voltage mains connections meeting both of the following conditions:

1. The HI and LO input terminals are connected to the mains under Measurement Category II conditions, defined below.
2. The mains are limited to a maximum line voltage of 300 VAC.

WARNING
IEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. DM858/DM858E may be used to make measurements with the HI and LO inputs connected to mains in such devices (up to 300 VAC), or to the branch outlet itself. However, DM858/DM858E may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltage’s that may exceed the  protection limits of the DM858/DM858E.
CAUTION
Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltage’s are also present on circuits that are isolated from mains. DM858/DM858E is designed to safely withstand  occasional transient overvoltage up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltage could exceed this level.
1.5 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.
1.6 Working Environment
Temperature
Operating: 0℃ to +50℃
Non-operating: -20℃ to +70℃
Humidity
≤80% RH, 40℃, without condensation
WARNING
To avoid short circuit inside the instrument or electric shock, never operate the instrument in a humid environment.
Altitude
Below 3 km
Protection Level Against Electric Shock
ESD ±8kV
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.
  Safety Class
  Class 2
