Section 3 Installation
DANGER
Only qualified personnel should conduct the tasks described in this section of the
manual.
3.1 Unpacking the Instrument
Remove the multiprobe from its shipping carton and inspect it for any visible damage.
Contact Customer Service at 1-800-949-3766 if any items are missing or damaged.
Note: It is normal for a small amount of solution to be in the cup.
3.2 Instrument Assembly
There are many ways to connect a multiprobe to a display or a personal computer.
DANGER
An electrical shock hazard can exist in a wet or outdoor environment, if the
multiprobe is powered via the external 115 VAC power supply. The safest and
preferred method of powering this equipment in wet or outdoor environments is
with battery or solar power (with a combined voltage not to exceed 15 volts). If it is
necessary to power the multiprobe with the 115 VAC power supply in a wet or
outdoor environment, a Ground Fault Interrupt (GFI) circuit is required. The
installation of the GFI device must be done by a licensed electrician.
1.
Remove all protective plugs and keep them in a safe place, they will be used again for
moving and storage.
2.
Connect the calibration cable (Cat. No. 013470), or detachable cable (015XXX) to the
multiprobe. The connectors are keyed for proper assembly. Align the bigger pin on the
multiprobe male connector to the indicator dots on the female cable connector. Do not
rotate the cable or force or twist the pins into the connectors to prevent damage to the
connector pins.
3.
Power the instrument by connecting the power receptacle from the calibration cable
and external power adapter to an approved battery or power supply (see
Figure 4 on
page 16 ).
4.
Connect the other end of the calibration cable, detachable cable, fixed cable, or
external power adapter to the computer serial port.
