Wireless Vacuum Gauge MG44

Quick Start
1. Unscrew the battery cover and install (2) AA alkaline batteries.
2. Hold to power on. Wireless setting is briefly displayed (ON/OFF). Activate wireless in the menu to send measurements to compatible Job Link® system tools.
3. Connect to the equipment you're evacuating. Connect directly to an unused service port or to a Schrader valve core removal tool.
4. View the live measurement on the top line. 5. Press NEXT to change bottom line view.
What's Included
(1) MG44 Wireless Vacuum Gauge (1) Reversible 1/4" angled (45°) coupler (2) AA Batteries (1) Operator's manual (1) Year limited warranty
! WARNINGS
Disconnect MG44 from system before applying pressure; pressures above 870 psig (60 bar) can damage the vacuum gauge.
Hand tighten fittings; overtightening may damage seals. Follow all equipment manufacturer's testing procedures above those in
this manual in regards to properly servicing their equipment.

Description
Use the MG44 Wireless Vacuum Gauge to reliably monitor your evacuations in the field. Long range wireless technology sends deep vacuum measurements up to 1000 feet (305 meters) away. View live on your SMANTM manifold, in the Job Link® mobile app, or directly on the MG44.
Save time by wirelessly monitoring your evacuations. Remotely view trending on the Job Link mobile app so you know when an extra nitrogen purge is required, a leak is suspected, or just watch everything pull as planned.
Reduce the misleading nature of dynamic vacuum measurement during pull down by connecting MG44 directly to the system. The reversible angled coupler makes it easy to orient the gauge so that it's out of the way and easy to see.
Select one of three unique views, including a new Rate Meter that provides a great feel and a Bar Graph that has a range up to atmosphere.
Built for demanding field use, the overmolded case resists damage from physical impact and water ingress.

Maintenance
CLEANING: Clean the exterior with a damp cloth. Do not use detergents or solvents.
SENSOR: Clean the sensor on a regular basis to prevent the build up of oils and contaminents. DO NOT use an object such as a cotton swab to clean the sensor. This may damage the sensor. 1. Power off MG44. 2. If attached, remove the coupler from MG44 to expose the cavity of
the 1/4" male fitting. 3. Fill up about half of the cavity with isopropyl (rubbing) alcohol or
AC system flush. 4. Cover the cavity and gently shake it for about 15-30 seconds. 5. Pour out the dirty solution and let the vacuum sensor dry with the
fitting facing down.
BATTERIES: An empty battery icon indicates batteries need to be replaced. When power is too low to operate, "LoBatt" is displayed 5 sec before powering off automatically. You can also monitor battery life in the Job Link app tool manager. 1. Power off MG44. 2. Unscrew the battery cover (2 screws) and dispose of batteries
according to local law. 3. Install (2) new alkaline AA batteries. 4. Reinstall cover.

GASKETS: Each end of the coupler is sealed by a black rubber gasket. These may become worn over time due to overtightening or connecting to damaged male fittings. 1. Use needle nose pliers or a similar tool to unscrew the Schrader
valve depressor from the gasket. 2. Remove and replace the worn gasket. 3. Screw the depressor back into the gasket.
Reversible Coupler
It's best to avoid using a hose to connect your vacuum gauge to the system. The coupler makes it easy to connect the gauge directly to a service port or valve core removal tool.
Each end has a valve depressor and gasket so you can flip the coupler to best fit the system and your viewing angle. Rotate and tighten each end independently for optimal viewing and control.

Operation
Buttons
Unless muted, each button press triggers a beep. An inactive button press triggers a double beep.
Hold to toggle power. Toggle backlight. Silence alarm.
Hold to enter MENU. Hold to exit MENU without saving. ENTER selection. Stop low alarm and start high alarm.
NEXT view. NEXT menu item or increase value. Hold to toggle ALARM mode. Silence alarm.

Display
In standard operating mode, the top line shows the live measurement. The bottom line shows one of three selectable views.
: Auto Power Off Enabled : Battery Level : Low Alarm : High Alarm : Muted : Rate (differential per minute) : Wireless Enabled (shown at startup) : Wireless Disabled (shown at startup) 07

Views
Press NEXT to change the content of the bottom line. Each view provides a unique way to monitor your evacuation.
RATE: The running 10-second average of the measurement's change per minute. Negative rates indicate the vacuum is getting deeper.
RATE METER: The graphical representation of the measurement's real-time change per minute. The scale is dynamic (i.e. relative to the measurement) making changes easy to see.
Decreasing
Stable
Increasing
BAR GRAPH: The graphical representation of the measurement. The scale is static and nonlinear for increased resolution at deeper vacuums. Full bars indicates atmospheric pressure.
~3500 micronHg

Alarm Mode
Every evacuation is different. Some require multiple purges of dry nitrogen, while some take less time than a phone call. Activate alarm mode so you can get other things handled without babysitting your gauge.
Follow recommended evacuation practices from the equipment manufacturer and training. Alarm levels can be adjusted in the menu.
1. Hold ALARM to activate* low alarm (L). Stopwatch starts. APO deactivates. Turn on your vacuum pump.
2. Once the low alarm level is reached, the backlight blinks and the alarm sounds. To silence the alarm, press or NEXT. Isolate the vacuum pump from the system.
3. Press ENTER to activate high alarm (H). Stopwatch restarts.
4. Once the high alarm level is reached, the backlight blinks and the alarm sounds. To silence the alarm, press or NEXT. Stopwatch stops.
5. Press ENTER to exit alarm mode. APO reactivates.
* Hold ALARM to exit alarm mode at any time. 09

Evacuation Tips
MAXIMIZE FLOW · Remove Schrader valve cores with a removal
tool. · Remove valve depressors from hoses. · Use shortest vacuum rated hoses with largest
diameter available. · Do not evacuate through hoses with low loss
fittings. TRUST YOUR TEST · Inspect the rubber seals at both ends of your
hoses for damage. Replace as needed. · Change pump oil before and during the job.
Change pump oil on-the-fly without losing vacuum with Fieldpiece vacuum pumps. · When the vacuum pump is isolated from the system, a slow rise that stabilizes may signify moisture is still present in the system. A continuous rise to atmosphere indicates a leak. Check hoses, tools, or the system itself. · Measurements are less representative of the entire system when the vacuum pump is on because pumping creates a pressure gradient. Isolate the pump and allow the system to stabilize before assuming the measurement represents the entire system.
