Omni Markers
The Tempo Omni Marker provides an improved method to electronically mark
and locate underground facilities. Unlike other marking devices that use just a
single coil, the Omni Marker contains three orthogonal tuned circuits. When
excited by any standard marker locator, these passive circuits produce a
uniform, spherical RF field in every direction. Because of their unique patented
design, the Omni Marker offers benefits that are superior to any other
electronic marking system. (See Figure 31)

Omni Marker & Uni Marker Signals
Omni Markers and Uni Markers each emit a distinct type of signal as shown in
Figures 32 and 33. Omni Markers produce a uniform, spherical RF field in
every direction, while Uni Markers emit dipole field signals primarily up and
down. (See Figures 32 - 33)

1. DESCRIPTION
This Instruction Manual Supports Firmware Version 1.0
The Marker-Mate™ EML100 Electronic Marker Locator is designed to locate
seven standard electronic markers including Tempo’s Uni Marker and Omni
Marker.
Features
• Five+ foot depth range
•Detects up to seven different marker types
•Scan mode provides simultaneous detection of all marker types
• Rapid switching between scan and single modes
•User-adjustable Detection Threshold
• Digital signal processor accuracy
• Large-character display
•Bar graph, numeric & audible signal strength indicators
•Adjustable speaker volume
• Headphone jack
• Battery level indicator
• Low battery warning
• Adjustable time out feature
• Weather resistant
• Rugged construction
Electronic Markers
Electronic markers vary in detection range. Markers are color coded as follows:
Power = Red
Water = Blue
Sanitary = Green
Telephone = Orange
Gas = Yellow
Cable TV = Orange/Black
Non-Potable = Purple
See Section 6, Compatible Tempo Markers, for details about Tempo’s Uni
Marker and Omni Marker.
Headset
The headset may be used to monitor the received signal in high noise level
areas when plugged into the jack provided. The normal speaker is de-activated
when a headset is used. Any standard stereo headset with a 3.5mm plug may
be used with the EML100.

EML 100 Mar ker Search Pattern
A search pattern should be used when locating markers. All marker locators
are dependent on the type of marker, depth of marker, and external noise as
to how broad of a footprint that can be detected. The highest probability of
locating a marker of unknown type and depth requires a tight search pattern.
Swing the locator in a comfortable 2 to 21/2foot arc; keeping the antenna
portion level to the ground. The speed of the swing and walk should be
moderate to allow full detection potential. For best results, perform some
sort of zigzag pattern as shown below. The edges of the swing should
come to the same point in allowing 100% coverage of the area. (See
Figure 28)
Awider search pattern can be used, but the larger the spacing between
passes the greater chance of not locating a marker.
Abenefit of using the EML100 in scan mode is that the search path can be
done once tightly to insure that all markers are found and identified. Compared
to a marker locator only able to detect one marker type at a time, the search
pattern would have to be repeated for each marker type.

Pinpoint Feature
The Pinpoint feature is used to adjust the gain of the EML100 to more closely
locate a marker.
Gain Adjust:
1. To eliminate noise or pinpoint markers reduce gain (press LO gain button).
2. Display indicates gain setting relative to 100%.
3. Continue pressing LO gain to reduce gain.
4. Press HI gain button to restore gain to 100%.
Note: Press LO gain button away from marker peak signal for best pinpoint
result.
Note: The Pinpoint feature will work
in the normal operation or SCAN
modes.
To activate the Pinpoint feature:
1. Select a marker MODE as
described in Unit Set Up
above.
2. When a marker has been
detected the display will show
a reading similar to the
“Normal Displays” shown in
Figure 26.
3. Without moving the EML 100,
press the DOWN arrow key to enter the Pinpoint feature. Press the UP
arrow key to return to the normal display.
a. The Bar Graph on the display will disappear temporarily and a per-
centage number will appear in the upper right corner. This percent-
age indicates the amount of gain remaining.
4. Continue searching the area and the Bar Graph will reappear as the
EML 100 is moved closer to the marker.
5. The Pinpoint feature may be used as needed until the exact location of
the marker is known.
Note: Activating the Pinpoint feature adjusts the gain horizontally and vertically.
If a marker is buried too deep, or has marginal signal strength, a reading may
not be possible using the Pinpoint feature even if the EML100 is directly over
the marker. Reset the gain by pressing the UP arrow key if no markers are
being detected.
Figure 27 shows samples of the displays that may be shown in various modes.

2. DISPLAY OVERVIEW
Note: x’s shown in the figures in this manual will be numeric readings on
the display.
LCD indicates:
• Mode: SCAN mode (with detected marker type shown), or single mark-
er mode (i.e. Power, Water, etc.) (See Figures 24 & 25)
•Numeric indication and bar graph
(See Figure 3)
•Gain Setting (See Figure 23)
•Volume adjustment for speaker res-
ponse (See Figures 4 - 7)
•Estimated battery life in hours and low
battery warning (See Figure 2)
• Time out feature with disable
(See Figures 16 - 20)
ON/OFF Switch
When the EML100 is turned on, the display will first show the firmware version
and then the estimated battery life remaining. (See Figure 2) After the Power-
On Sequence, the unit will default to the mode and settings that were used last.
For example, if the unit was last used to locate Gas markers with the Volume
set on Low, it will return to the same settings. (See Figure 3)
Menu Key
Note: The EML 100 is active as soon as it is turned on and completes the
Power-On Sequence. The bottom line of text on the display shows available
options when using the MENU Key.
Press the MENU key to cycle through the following 4 sub-menus :
Volume Control
Use the Up or Down Arrow keys to select Off, Low, Medium, or High and use
the EXITkey to exit the MENU screen. (See Figures 4 - 7)
Pressing the MENU Key again will display the MODE Select menu.
