Safety Cautions
For safe use of this gauge, be sure to read this manual and the following safety
cautions.
Turn off power.
If the gauge is damaged, immediately turn off the power.
Otherwise, fire or electric shock can result. For safety reasons,
contact your local ULVAC representative or ULVAC JAPAN.
Turn off power.
If the gauge gets unusually hot or gives out smoke, immediately turn
off the power. Otherwise, fire can result. For safety reasons,
contact your local ULVAC representative or ULVAC JAPAN.
Turn off power.
Whenever you touch or may touch the sensor head terminal on the
rear of the controller, turn off the power to the gauge. A grid voltage
of 150 VDC is applied to the sensor head terminal. If you touch it
when power is turned on, you will get electric shock.
Turn off power.
Whenever you touch or may touch the sensor head pin, turn off the
power to the gauge. A grid voltage of 150 VDC is applied to the
sensor head terminal. If you touch it when power is turned on, you
will get electric shock.
Beware of high temperature.
Do not touch the sensor head surface, which is very hot during and
immediately after operation. If you touch it, you may get burned.
Turn off power.
Turn off the power before replacing a fuse. If it is replaced with the
power turned on, you may get electric shock.
Turn off power.
Before installing the gauge, unplug the power cable.
Use fuse of specified rating.
Do not use a fuse other than specified one nor short the fuse holder.
Damage or fire can result.
Check line voltage.
Before turning on power to the gauge, make sure the vacuum gauge
operating voltage and the supply voltage are in agreement.
Connection with an incorrect power can damage the vacuum gauge
or fire.
Be cautious with operating environment.
Do not connect the sensor head to an environment where pressure
exceeds atmospheric pressure. If the pressure in the sensor head
exceeds atmospheric pressure, the sensor head will be damaged and
the sensor head will pop out from the connection, causing damage or
injury to human body and other hazards. In that event, provide an
isolation valve or other so that the pressure in the sensor head does
not exceed atmospheric pressure.
Don
′
t disassemble.
Do not disassemble the vacuum gauge (controller, sensor head cable,
and sensor head)
Don ′ t modify.
Do not modify the vacuum gauge (controller, sensor head cable, and
sensor head). If it is modified, its action is not warranted. Also fire
or electric shock can result.
Check connection.
For safety reasons, connect the grounding terminal of the controller
to ground.
