Glossary
Words and phrases Definitions
Absolute Isolated pressure
(AI)
Absolute pressure is equal to the sum of these two:
1. Gauge pressure.
2. Atmospheric pressure
(also known as barometric pressure).
Button or key •A
button
always refers to an area on the screen that you can
click to select functionality.
•A
key
always refers to hardware push-buttons on the keyboard
that you can press.
Compound Isolated pressure
(CI)
A compound gauge can display both positive and negative
(vacuum) pressures. The meriGauge plus System replaces the
need for buying one gauge for each sensor:
1. A pressure sensor.
2. A vacuum sensor.
Firmware Firmware is a type of software that is stored on hardware. Both
meriGauge plus and meriSense have firmware. meriLink is a
software application that can communicate with their firmware and
change or update it as needed.
Isolated The word isolated refers to the sensing element being isolated
from the media. It is commonly used in the phrases Absolute
Isolated (AI) pressure and Compound Isolated (CI) pressure.
Meriam Calibration Meriam calibration refers to any calibration completed at Meriam
with Meriam traceability. Meriam calibration includes:
•Oven calibration.
•Multipoint Meriam adjustment.
User Calibration User calibration refers to any calibration done outside of Meriam
with non-Meriam traceability. User calibration includes:
•Multipoint user calibration or adjustment.

The meriSense detachable sensors
Make a pressure connection
Make a good NPT connection
Each meriSense detachable sensor has a 316 stainless steel
1/4 in. male NPT connection for direct mounting.
•The threads should be coated with a pipe sealant
compound before installation.
•Tighten to finger tight plus 1.5 turns to 3 turns using a
23 mm (7/8 in.) wrench with the notch facing the same
direction as you intend for the display.
Use only a wrench on the hex fitting
Never rotate a meriSense sensor by turning the meriGauge
plus gauge.
Protect your sensors from dust
Keep the dust cap on sensors
Make sure you put the dust cap on the sensor to protect the
electrical contacts after the meriGauge plus gauge has been
detached from the sensor.

Pressure limits
Pressure limits
•Do not exceed the pressure limits listed in the sensor pressure
ranges section for the MS700 meriSense.
•Failure to operate within the specified pressure limits could
result in injury.
Overrange limit
Overrange pressure means the value is outside the calibrated
upper or lower range.
•Up to 110 % of range, meriGauge plus displays the accurate
pressure.
•Above 110 %, it flashes red. This indicates that the applied
pressure exceeds the calibrated range.
Note: If the calibrated pressure range is exceeded,
the pressure displayed may not be accurate
•Above 120 %, it flashes red and displays dashes.
Overpressure limits
Overpressure is the point at which permanent damage
(deformation) may occur to the sensor.
Burst pressure limit
Burst pressure is four (4) times the rated pressure. It is the point
at which the sensor may mechanically leak.

Inspect the vent on the sensors
Do not block vent
1. If the vent becomes blocked, it will cause inaccurate
measurements.
2. Meriam recommends that you visually inspect the vent
area each time you use the meriSense to make sure it is
not blocked.

Batteries
Install the batteries
1. Turn over the meriGauge plus so the display faces down.
2. Remove the four screws on the battery cover with the
Phillips head screwdriver by turning them
counterclockwise.
3. Insert the four AA batteries.
Note: Pay attention to the positive (+) and
negative (−) battery polarity markings at the bottom
of the compartment.

Know your batteries
The meriGauge plus is powered by four 1.5 volt AA size
batteries.
•Never mix batteries—not by manufacturer or by size, by
capacity, or by chemistry.
•Never mix old and new batteries.
•Remove all four batteries in the meriGauge plus at the
same time.
•Replace all four batteries with batteries from the same
package or with the same expiration date.
