730 Bubbler Module
Section 1 Introduction

1-2

1.2 Connecting to the

Sampler

To install the module:

1. Turn the sampler off.

2. Remove the connector cap in the module bay and move it

aside.

3. Slide the module into the bay.

4. Push against the module to be sure the connector is fully

seated.

To remove the module:

1. Turn the sampler off.

2. Press the silver button on top of the module and pull the

module from the bay.

3. Replace the connector cap in the module bay.

1.3 Installation Checklist

1. Check the desiccant cartridge. Make sure the desiccant is

active (blue in color) and remove the red cap.

2. Install the module and turn the sampler on.

3. Install the bubble line in the flow stream.

4. Connect the bubbler line to the module.

5. Program the sampler and calibrate the module’s level read-

ing.

6. Run the program.

Note

You should install the module before turning the controller on.
When the controller is turned on, it looks for a module. The
controller will not recognize a newly installed module if it is not
seen during this power-up routine. If you install a module while
the controller is already on, turn the controller off and then on
again to reconfigure the controller to use with the module.

1.4 Calibrating the

Bubbler Module

After the sampler, module, and bubble line have been installed at
the site, calibrate the module by measuring the depth of the
water and adjust the reading to match.

It is possible to calibrate the module in a container of water. Use
a bubble line of the same length as the one at the installation site
to get an accurate and reliable calibration.

1.5 Power Consumption

The 730 Module consumes a considerable amount of power. A
nickel–cadmium battery may not be sufficient to finish a sample
routine. For example, the battery should be expected to complete
three sampling routines of 24 samples, each sample 200 ml, at
one sample per hour with a 10 foot suction line and a 5 foot head.
But if the routine is changed to 24 samples, 4 samples per bottle,
each sample 250 ml, at 15 minute intervals, with the same
suction line and head height, the battery does not have the
capacity to complete one routine
. Teledyne Isco recommends
using a lead–acid battery or a 913 or 923 power pack when using
the 730 Bubbler Module.
