WARNING
Do not operate the instrument in the presence of flammable gases or fumes.
Operation of any electrical instrument in such an environment constitutes a
definite safety hazard.
WARNING
Do not use the instrument in a manner not specified by the manufacturer.
To Set Up the Probe
This instrument is provided with a three- wire power cable. When
connected to an appropriate ac power outlet, this cable grounds the
instrument cabinet. The type of power cable plug shipped with the
instrument depends on the country of destination. The 1142A
Power Control and Power Module does not have a power switch. A
power switch is not required because of the low mains power
requirement.
NOTE
The 1141A/1142A probe system (specifically the 1142A) requires a power source
of either 115/230 Vac, 47 to 440 Hz, 25 VA maximum.
CAUTION
Before connecting power to this instrument, be sure the line voltage switch on the
instrument’s rear panel is properly set as described in this section.
1
Verify the setting of the
LINE SELECT
switch on the 1142A’s rear
panel. The slide switch can be set to either 115 or 230V. See
Figure 3 on page 12 for the location of the switch.
WARNING
Before connecting this instrument, the protective earth terminal of the
instrument must be connected to the protective conductor of the (Mains) power
cord. The Mains plug must be inserted in a socket outlet provided with a
protective each contact. The protective action must be negated by the use on an
extension cord (power cable) without a protective conductor (grounding).
Grounding one conductor of a two-conductor outlet does not provide an
instrument ground.
