2.3 Safety Symbols
The signs and symbols on the multimeter, which provide guidelines for safety and
handling, are displayed and described below.
This symbol advises the user of a possible danger area.
Please consult the manual (see “Connection of Measurement
Leads” and Chapter “Operating Instructions”).
This symbol makes the user aware, that a dangerous
voltage can be present at measurement connectors.
The CE mark means, that the manufacturer has issued an
EC Declaration of Conformity for this multimeter. This declaration
certifies, that this multimeter conforms to the pertinent requirements
of EC directives.
2.4 Accident Prevention
While using this measurement unit, precautions to prevent an accident should be
taken, appropriate to the use of a measurement device.
It is especially important to observe , that during current measurement, a very low
impedance i.e. 0.1Ωexists between the Hi and Lo connectors, so that a cur-
rent/voltage, which is applied to the Hi connector, can be contacted by a cable that is
connected to the Lo connector.
2.5 Connecting the Unit to Main Power
This PREMA measurement unit is designed to be connected to AC Main Voltage, at a
frequency of 50 Hz or 60 Hz. The rear panel of the unit is equipped with a standard
DIN grounded power connector.
!

Grounding
_____________________________________________________________________________________________________________________________________
2-4
Before connecting the unit to power, you should make sure that it is set to the right
voltage (indicator and fuse).
The voltage selection switch with integrated fuse is located right under the power
connector, where you can also read off the current voltage setting; a setting of
"220V" represents an AC voltage from 220V to 240V, "110V" represents a voltage
from 100V to 120V.
Switching the AC Voltage is done as follows:
)1. Unplug the unit.
2. The clamp for the fuse is located between the plug and the power selector and
must be removed. For a setting of "110V" you will need a fuse rated at 0.4A;
for "220V" you’ll need a fuse rated at 0.2A.
3. Place the necessary fuse in the clamp and push the clamp back in.
4. Turn the cylinder with the voltage indicators once left or once right to the de-
sired setting, so that the voltage that is currently set is indicated by the white
arrow on top.
The indicators are used as follows:
Setting Voltage Range
110 V 90 VRMS to 130 VRMS
220 V 180 VRMS to 265 RMS
Table: Main Voltage Ranges
2.6 Grounding
In order to protect the user, the unit’s case is grounded through the grounding lead of
the power cable. To ensure proper grounding, the power cable should always be con-
nected to a properly grounded power connector.
The unit case is galvanically separated from the measurement connectors and inter-
face ports.
The back of the unit is equipped with a grounded screw, identified by the sym-
bol, where the user can connect a separate ground line (rack mounting bracket).

2.7 Warranty
PREMA warrants the reliable function of the unit for a period of two years from the
date of delivery.
Repairs that need to be carried out during the warranty period are not billed to you.
Damage caused by inappropriate use of the unit, or by surpassing specified limits,
does not fall under PREMA’s warranty obligations.
Please be aware, also, that PREMA will not be held liable for damages, incidental or
coincidental, associated with the use of this measurement device.
2.8 Certificate
Each Digital Multimeter 5017 is provided with a calibration certificate at the factory,
certifying the location, date, and traceability of the unit’s calibration to the user.
Please look for this certificate at delivery time. It can also be useful as a control for
yearly recalibrations, since PREMA warrants that the unit will remain within specifi-
cations for one year, and recommends recalibration after that time.
2.9 Turning it on
The multimeter can be switched on with the STANDBY KEY after connecting the power
cable. A device setting with measurement function, range and time can be stored as a
power-on setting in the "Configure Menu, Settings, Save Settings".
Switch off the instrument also with the STANDBY KEY.
The 5017 is then in standby mode. The red LED at the bottom left of the front panel
lights up.
The analog board of the unit is provided with power, even in standby mode, so that no
warm-up time needs to be taken into account when the unit is turned on.
Otherwise, warm-up times, as provided in Chapter “Technical Specifications”, should
be heeded.
Note: The transformer is not disconnected from Mains Power in standby
mode.
The instrument starts automatically with power-on after switching-
off the unit by pulling the power cord.

Connection of Measurement Leads
_____________________________________________________________________________________________________________________________________

Operation with rear panel inputs and Scanner
If the 5017 is to be operated from the rear panel inputs or the built-in scanner, please
proceed as follows:
)1. Please remove all measurement cables from the connectors and
unplug the unit.
2. Turn the unit upside down, so that it is lying on its top shell.
3. Remove the four screws from the unit case's bottom shell.
4. Remove the unit case's bottom shell.
5. Tightly grasp and remove and then swap the two front-rear cable-set connec-
tors that are visible on the left, as seen from the front panel of the unit. Only
the rear cable-set connector is connected to the preamplifier input circuitry.
The front cable-set connector is essentially a place-holder for the input that is
not being used.
6. While re-sealing the case, make sure that no wires are caught anywhere.
After turning the unit on (of course, you should first re-seal the unit’s cover) the
channel indicator field in the display will show the indication “REAR,” or a channel
number (if the Scanner is installed).
The software automatically checks for any rear-panel connections when the unit is
turned on and tests if the cable set connector has been moved from front panel input
to rear-panel input.
2.11 Rack Mounting
A rack adapter with two height units is offered for the 5017. The unit has a width of
one-half 19-inch, so it can be combined with another half-19-inch unit. More infor-
mation about rack mounting can be found in the Chapter “Accessories.”
When installing the unit into a 19-inch rack, you should take into account, that the
ventilation openings in the back are not covered up. In addition, it should be possible
to cut power to the unit in an emergency, through the use of an EMERGENCY OFF
switch somewhere nearby.
Note: When the unit is installed in a 19-inch rack, and is to be operated through
the rear panel inputs or the Scanner, please make sure that the front-rear
cable-set connector in the unit has been connected to rear-panel input, prior
to installing the unit into the rack (see the previous section on
“Connection of Measurement Leads”).

2.12 Miscellaneous
Conforming to the Norm EN 61010
The Digital Multimeter 5017 is produced according to EN 61010. This means the
highest possible level of safety for the user, in relation to “dangerous body currents,”
“high temperatures,” and “mechanical endangerment".
This has the consequence, that this unit cannot be switched from front-panel to rear-
panel input with a switch, as is found with multimeters of other brands.
The minimum of 5.5mm clearance and creepage distance at a nominal voltage of
1000Vdc is not implemented by standard slide switches. When 1000V are applied to
the front input connectors, and a switch to the rear input connectors is effected by
slider switch, a dangerous transfer of high voltage from the front inputs to the rear
inputs can occur.
In our opinion, the manual re-positioning of the Front-Rear cable-set connector is not
the most elegant, but certainly the safest solution at the moment. This does not mean,
however, that PREMA will not come up with a completely new solution in the future.
Scanner with Model 5017SC
For the model 5017SC with integrated scanner it is important to take the DC and AC
voltage limits of the Scanner into account, depending on which option is installed.
The input voltage at the rear panel is limited to 125 Vpk with the standard scanner
option.
The limit of 1000Vpk continues to be valid for the front input connectors only.
Current measurement and the 1000V range can only be selected while using the front
input connectors .
