1 Basic Gage Features
Keypad Functions
The figure below shows the full keypad layout representative of the MTG-99 Hall Effect
thickness gage.
The following table refers to each key or symbol shown on the keypad. Note the F keys
correspond to text above each key and prompts change depending on which screen you
are adjusting.

F1, F2, F3 and F4, these keys are called soft keys and correspond
to text above the keys while making adjustments in various
screens.
At the top of the unit is the probe connection, on the top right, mini
usb and optional footswitch or rs232. Also available as a hardware
option is internal Bluetooth to communicate via Bluetooth
(requires separate receive device).
Function Keys
Function keys, or F keys (e.g., F1, F2, F3, F4), have various gage functions and may
change depending on the display screen. View the bottom of the display screen for the
function that corresponds with the appropriate F key. For example, F1 may correspond
with the Save Thickness function, F2 with the Freeze function, or F3 with the Clear
MNMX (clear min/max) function. Many times the left or right arrow keys can be used
instead of the MENU/OK key to highlight a parameter or to see what is under the
selected choice.
Battery Pack
To ensure the highest level of performance and protection, the battery compartment is
separated from the electronic components of the gage.
Monitoring the Battery Charge from the Display Screen
The MTG-99 continuously displays the percentage of battery life remaining on the
bottom right corner of the measurement display screen. When the battery life is below
10%, the battery indicator will turn from green to red. When the battery life is below 5%,
the indicator will flash.
Note: Power off the MTG-99 series gage to ensure any saved data is stored internally.

Re-charging the Battery
To re-charge the battery, simply plug in the charger to an AC outlet (between 100-240V)
and plug the other end into the USB connector on the top of MTG-99 gage. The F4 key
will light up with a blue LED when charging, and the light will go out when fully
charged. Allow several hours (up to 10 hours) to fully charge.
Note: There is a battery indication monitor on the bottom right of the screen showing the
percent of battery life, as seen below at 75%.
You may also use a computer instead of the wall charger to charge the gage, but this will
take significantly more time than using an AC outlet. If you decide to charge the gage

using this method, make sure the gage is powered off before you connect the USB to the
computer and to the gage itself.
When charging is complete, the F4 key will appear translucent in color. Power off the
gage, and unplug the charger from the USB connector on the top of the gage.
Using Non-rechargeable AA Batteries
A non-rechargeable alkaline AA pack is also available. This option requires a spare tray
and 3 AA batteries. Follow these steps to insert non-rechargeable batteries:
1. Un-screw the battery door.
2. Disconnect the Li-Ion battery connector.
3. Plug in the AA tray connector.
4. Replace the battery door and tighten screws.
Note: When using the 3 AA battery tray, batteries cannot be re-charged.

Boot, Bail, and Strap Features
The custom rubber boot with built in bail and 4-point chest harness is an accessory for the
MTG-99 gages. Not only does the boot help to protect the gage from the elements, but
the functional bail and strap also offers a variety of positioning options.
Placing the Boot on the Gage
To insert the gage into the rubber boot, follow these steps:
1. Guide the gage strap through the hole at the top of the boot (either right or left
side).
2. Slide the gage into the top of the boot.
3. Gently apply pressure to the bottom of the gage until it fully pops into the boot.
Removing the Boot from the Gage
Be sure that the bail is set in the open position before attempting to remove the boot.
Follow these steps:
1. Apply pressure to the bottom two corners of the boot until the gage pops out.
2. Wriggle the top section of the gage out of the boot.
3. Guide the gage strap through the hole at the top of the boot.
Using the Boot Strap and Bail
The boot strap is attached to the bail on the back of the boot. It can be used as a right- or
left-handed strap, or a finger strap. You can also connect the strap to a 4-point chest
harness for hands-free use.
The bail, including the straps, can be removed from the boot. This is useful when adding
accessories or locating the gage’s serial number. Simply open the bail and apply gentle
pressure to one side of the connector, which is located at the top of the bail. The piece
will pop off exposing the accessory mount (see below) and gage serial number.
Other Gage Features
Locating the USB Slot
MTG-99 gages are furnished with a USB 2.0 slot on the top of the gage. Use the USB
slot to connect AC chargers or to connect to a computer for cross-functionality.
Using the Accessory Mount
On the back of the gage is a ¼ x 20 accessory mount. This connector point is compatible
with a multitude of accessories including a magnetic pipe attachment and a Gorilla Pod.
Locating the Altitude Change Release Regulator
At the bottom of the gage is a circular outline with small holes. This feature regulates
pressure due to altitude change. Any pressure built up inside the gage will be
automatically released.
