M130 – T/C Calibrator
Introduction
Thank you for purchasing this Meriam product. Meriam has been providing
innovative, reliable, cost-effective measurement and calibration solutions
since 1911.
The M130 Thermocouple calibrator has been designed using the latest
technology to provide reliable accuracy throughout its entire operating
temperature range, dependable operation, and exceptional battery life.
The compact design makes the unit easy to carry and the intuitive user
interface makes it easy to use.
Temperature measurements/simulations are displayed on a large, easy-to-read
liquid crystal display (LCD). This unit has two backlights: a green backlight
which is user activated to improve readability in low light conditions, and an
automatic red backlight which indicates an over-range condition.
Twelve keys provide access to the functional modes and menus, including
Measure, Simulate, Setup, Run, Record, Edit, and Backlight activation. A list
of these functions is printed on the back of the case.

M130 – T/C Calibrator
Certification
The M130 is EMI/ESD compliant to the test specification EN61326.
The M130 is for general purpose use only. Do not use in potentially hazardous
atmospheres.
Instruction Manual Z1017-IR
E.O. 6566 Sept. 2008
Changing the Batteries
The M130 is powered by three, 1.5 volt AA size batteries. The “BAT” icon in
upper left of display will activate when battery output drops below a threshold
level. Approximately 2 hours of life remain from that point.
Replace all three AA batteries at the same time for best performance.
To replace the batteries, locate the battery compartment at the lower rear of
the M130. Remove the screws located at the top center and bottom center of
the battery cover by turning them counterclockwise until fully disengaged
from the M130 base. Remove the cover. Do not remove the pink anti-static
foam that is attached to the inside of the battery cover. This foam is
necessary to properly secure the batteries under specified shock and
vibration conditions.
Remove the batteries by pulling the positive side first straight out of the
battery compartment. Note the positive (+) and negative ( – ) battery polarity
markings at the bottom of the compartment, as shown below.
www.meriam.com
Page 18 of 21
M130 – T/C Calibrator
Instruction Manual Z1017-IR
E.O. 6566 Sept. 2008
Install the three batteries by sliding them into the bottom of the battery slots,
positive (+) end first, making sure the polarity markings on the batteries align
with the markings molded into the battery compartment. When a battery is
installed with the polarity reversed, the stand-offs prevent the negative battery
terminal from contacting the positive terminal in the battery compartment.
The unit will not power up in this condition; to correct, simply reverse the
battery to correct the polarity.
With the batteries secured in the battery compartment, replace the
compartment cover. The cover has only one orientation for correct alignment.
The “WARNING
battery cover must be visible and aligned in the approximate middle of the
M130 case. To secure the cover, torque the screws clockwise to 1.6 in-lbs.
Do not over tighten.
