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 maximumof 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 resistancemeasurements. 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: 200
Vpk.

DM858 Series Quick Guide
2

Copyright ©RIGOL TECHNOLOGIES CO., LTD. All rights reserved.

Safety Requirement

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 aprotection limit of 10 A(DM858)/3 A(DM858E) maximum current flowing through theterminal 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 witha 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.
WARNINGIEC 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 otherdevices that plug into a branch outlet or socket. DM858/DM858E may be used to makemeasurements 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 themain circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors.
Such devices and circuits are subject to overvoltages 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 overvoltages are also present on circuits that are isolated from mains.
DM858/DM858E is designed to safely withstand occasional transient overvoltage up to2500 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 andoutlet 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 andbehind 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 andinspect the air outlet and the fan regularly.

1. Disconnect the instrument from all power sources.
2. Clean the external surfaces of the instrument with a soft cloth dampened with mild
detergent or water. Avoid having any water or other objects into the chassis via theheat dissipation hole. When cleaning the LCD, take care to avoid scarifying it.
CAUTION
To avoid damage to the instrument, do not expose it to caustic liquids.

WARNINGTo avoid short-circuit resulting from moisture or personal injuries, ensure that the
instrument is completely dry before connecting it to the power supply.

To Replace Current Input Fuse
The instrument is equipped with a current input fuse on the front panel. The fuseprovides a protection limit of 10 A (DM858)/3 A (DM858E) maximum current input.
When the input current exceeds 13.5 A (DM858)/4 A(DM858E), the fuse is blown. To
replace the fuse, follow the steps below:

1. Power off the multimeter and remove the power cord.
2. Use a slotted (flat head) screwdriver to turn the fuse holder in the direction asshown in the figure below and remove it from the instrument.
3. Replace this fuse with a fuse of the specified rating.
4. Re-insert the fuse holder into the instrument.
