Notes on Use

WARNING
Before turning on the power, make sure that the voltage of the power
supply being used matches the supply voltage indicated on the rear
panel of the unit. (3155: specified at order, 3155-01: set by the voltage
selector)
If an attempt is made to use an improper supply voltage, there is danger
of damage to this unit and of life-threatening risk to the operator.
The unit is constructed so as to be connected to a ground line via a
three-core power cord that is supplied with the unit. In order to avoid
electric shock, connect the unit to a properly grounded (3-pin) outlet
using the power cord provided.
Before using the unit, make sure that the sheathing on the leads /
probes is not damaged and that no bare wire is exposed. If there is
damage, using the unit could cause electric shock. Replace the lead /
probe with the specified 9195 or 9170, or optional 9461 or 9287.
To avoid the danger of electric shock, never operate the unit with a
measurement network removed.
Do not swithc the voltage selector when the power is turned on.
CAUTION
Do not press hard upon the touch screen, or operate it using a hard object or
one with a sharp end. Doing so could scratch or damage the screen or the
soft keys.
NOTE
Notes on Use
In order to ensure safe operation and to obtain maximum performance from
the unit, observe the cautions listed below.
Before measurement
・ Of the three optional Measurement Networks (9497, 9498 and 9499), one
must be installed with the 3155 or no measurements can be made. If the
power to the 3155 is turned on without having installed one of the networks,
the message ’Measurement Network not installed.’ will appear on the LCD.
In which case, please install a measurement network as described in Section
4.1, "Installing the Measurement Network."
・ Because the current consumption monitor is AC coupled, errors occur when
measuring an AC current which includes a DC offset. (Example: half-wave
rectified current)
