3.1.4 Opening the Case To access the flow meter controls and internal plotter, you must

open the case. Unlatch the two catches on the right side of the

case and pull open the lid. You will need to open the case

whenever you change the plotter chart or change the pro-

gramming with the keypad. You can read the display through the

window, so periodic readings may be taken without opening the

case. Again, do not allow the flow meter to operate routinely with

the door open.

3.2 Connection to a Power Source

The 4220 requires a 12-volt, direct current (12 VDC) power

input. This power may come from various sources:

• Companion Isco Wastewater Sampler

• Isco Nickel-Cadmium Battery

• Isco Lead-Acid Battery

• Isco AC Power Supply

• External 12 VDC battery, such as a deep-cycle marine or

RV type

Detailed information on power sources is provided in the Power

Products Guide provided with this manual. The procedures for

connecting all these power sources to the flow meter are dis-

cussed in the following sections.

3.2.1 Low Power Indication When power to the flow meter falls too low for the unit to operate

properly, the message POWER LOST/LOW BATTERY will

appear on the top line of the display. When power is lost or falls

below operating limits, the flow meter will stop measuring level,

the display will go blank, and the internal printer will not be able

to print. However, the internal battery-backed RAM will retain

program selections you have entered and also stored data in

memory, if there is any. (Note that you must be using Flowlink

software for any data to accumulate in memory.)

3.2.2 Isco Sampler If you combine a 4220 Flow Meter with an Isco Wastewater

Sampler in a flow-proportional sampling system, you can power

the flow meter from the sampler's power supply. Connect the flow

meter to the sampler with the Isco flow meter-to-sampler cable.

This cable attaches to the SAMPLER connector on the flow meter

and the FLOW METER connector on the sampler.

The flow meter will then receive power from the sampler. Keep in

mind that under certain conditions, such as a fast setting on the

internal printer’s chart speed, the flow meter will draw a signif-

icant amount of power from the sampler's battery. In such cases

it is better for the flow meter have its own battery.
