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 .
