Introduction

Congratulations on the purchase of your new 8890/8891 Locator. The 889X Series

Locator is specially designed to detect passive electronic markers.

The R eceiveR detects the signal. You can locate the relative position of the buried marker by locating the point of the highest signal.

Electric shock hazard:

!

WARNING

• Tool is designed to detect electromagnetic field emitted from buried metallic utilities. There are buried cables, pipes, and utilities this instrument CANNOT detect.

• LOCATING is not an exact science. The only certain way to be sure of the ex- istence, location, or depth of buried utilities is to carefully expose (dig up) the utility.

• De-energize any circuits in or around the work area.

• Do not expose tool to rain or moisture.

• Use tool only for intended purpose as described in this manual

Failure to observe these warnings could result in severe injury or death.

Locating

Locating A Passive Electronic Marker

It is ideal to have a general idea of where a marker may be buried. By first locating the utility, the user has a path in witch the marker is buried.

Select desired gain setting. Most markers may be located on lowest gain setting. Use high gain if marker is known to be deep.

Move the R

ECEIVER at a medium speed side to side while walking a straight line.

Move slowly so a marker may not be missed. The R

ECEIVER will detect a marker just a few feet away so a grid search may be needed to find a marker.

The R

ECEIVER will g ive a maximum signal when d irectly over t he m arker. GAIN adjustment may be needed for optimum sensitivity.

N OTE : I T IS POSSIBLE TO DETECT AN ON TARGET MARKER.
