Unpacking and Setting Up the System

Checking the Zero of the Pressure Gauge
The pressure gauge is adjusted to the zero position at the factory;
however, if the needle is not lined up with the left side of the zero
box marked on the gauge, you will need to re-zero the pressure
gauge (see Figure 3-1).
If zeroing is required, follow the steps below to reset the gauge:
1.
You will need a palm-sized square of soft, clean rubber to grip
the front surface of the gauge and a .050 inch hex wrench
(included in the accessory kit).
2.
Hold the cabinet for support and grip the front surface of the
gauge with the square of rubber in the palm of your hand.
3.
Unscrew the front cover of the gauge in a counter-clockwise
direction.
4.
A sockethead setscrew is located under the bottom of the gauge
panel where it is marked “zero”.
5.
Adjust the setscrew until the needle lines up with the left side of
the zero box marked on the gauge.
6.
Reassemble the front cover of the gauge.

Connect the AC power cord (supplied) to the AC POWER IN
connection on the back of the Electrospray and then into an
available power outlet. It is not necessary to select the correct
voltage, the instrument accepts line voltages of 85 to 260 VAC,
50-60 Hz, 25 W max., single phase. The connector has a built-in
on/off switch.
Note
: Make certain the line cord is plugged into a grounded (earth
grounded) power outlet. Position the Electrospray so the power
cord connector is not blocked and is easily accessible.
Note
: The Electrospray power supply contains no user-serviceable
parts. If the power supply is not operating correctly, use the
information in
to contact TSI. This instrument should
not be used in a manner not specified by the manufacturer.
Toggle the on/off switch at the AC POWER IN connection to the on
position to verify the instrument has power.
