Safety notes
Please read this manual carefully and completely before you use the device for the first time. The
device may only be used by qualified personnel and repaired by PCE Instruments personnel.
Damage or injuries caused by non-observance of the manual are excluded from our liability and
not covered by our warranty.
•
The device must only be used as described in this instruction manual. If used otherwise,
this can cause dangerous situations for the user and damage to the meter.
•
The instrument may only be used if the environmental conditions (temperature, relative
humidity, …) are within the ranges stated in the technical specifications. Do not expose
the device to extreme temperatures, direct sunlight, extreme humidity or moisture.
•
Do not expose the device to shocks or strong vibrations.
•
The case should only be opened by qualified PCE Instruments personnel.
•
Never use the instrument when your hands are wet.
•
You must not make any technical changes to the device.
•
The appliance should only be cleaned with a damp cloth. Use only pH-neutral cleaner,
no abrasives or solvents.
•
The device must only be used with accessories from PCE Instruments or equivalent.
•
Before each use, inspect the case for visible damage. If any damage is visible, do not
use the device.
•
Do not use the instrument in explosive atmospheres.
•
The measurement range as stated in the specifications must not be exceeded under
any circumstances.
•
NEVER apply voltage or current to the meter that exceeds the specified maximum:
Input Protection Limits
Function
Maximum input
V DC or V AC
1000 VDC/AC RMS
mA AC/DC
500 mA 1000 V fast acting fuse
A AC/DC
10 A 1000 V fast acting fuse (20 A for 30
seconds max. every 15 min)
Frequency, resistance, capacitance,
duty cycle, diode test, continuity
1000 VDC/AC rms
Temperature
1000 VDC/AC RMS
Surge protection
8 kV peak in line with IEC 61010
•
USE EXTREME CAUTION when working with high voltages.
•
DO NOT measure voltage if the voltage on the “COM” input jack exceeds 1000 V above
earth ground.
•
NEVER connect the meter leads across a voltage source while the function switch is in
the current, resistance, or diode mode. Doing so can damage the meter.
•
ALWAYS discharge filter capacitors in power supplies and disconnect the power when
making resistance or diode tests.
•
ALWAYS turn off the power and disconnect the test leads before opening the covers to
replace the fuse or batteries.
•
NEVER operate the meter unless the back cover and the battery and fuse covers are
in place and fastened securely.
•
If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
•
Do not use the meter or test leads if they look damaged. Use extreme caution when
working around bare conductors or bus bars.
•
Accidental contact with the conductor could result in electric shock.
•
Be careful when working with voltages above 60 V DC or 30 V AC RMS. Such voltages
pose a shock hazard.
