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.

Keypad Functions
ON/OFF Key
The ON/OFF key, represented by the standard ON/OFF symbol,
turns the M130 ON or OFF (note: the ON/OFF key must be held until the
display turns on or off). Upon power on, the M130 will perform a self-test,
displaying the Meriam product ID, and all segments for approximately 1-2
seconds, then go into the mode in use when unit was powered off. The
firmware version is displayed at the end of the self-test.
BACKLIGHT Key
The BACKLIGHT key, represented by the standard light-bulb
symbol, turns the green display backlight on and off. The backlight will
remain on for approximately 20 seconds if not manually turned off. To
override the auto shut off timer, press and hold the BACKLIGHT key to turn
the backlight on. After holding the key for approximately 2 seconds, the
backlight will flash off and back on. Release the key now and the backlight
will remain on until manually turned off or until power is cycled.
SETUP Key
The SETUP key enters or exits the setup mode and is also used to go
back one menu level. The SETUP icon is displayed while in the setup mode.
Setup menus are shown in the bottom (alpha-numeric) row of the LCD. The
SETUP key also ends simulation activities.

FUNCTION Key
The FUNCTION key, represented by the FUNC symbol, selects one
of 3 functional modes: Measure, Simulate (manual), or Simulate (auto), and
displays the corresponding icons (MEAS, SIM). This key can also be used to
advance one menu item or will advance to next recorded value while in
RECORD view mode.
UNITS Key
The UNITS key selects the engineering unit of
measurement/simulation desired for temperature probes: °F, °C, °R, and K.
The UNITS function is only available when the M130 is actively measuring or
simulating temperature signals. This key is also used to go back one menu
item in SETUP or back to the previous recorded value while in VIEW mode.
ENTER Key
The ENTER key accepts the currently displayed item/value
during setup activities. During active simulation activity, the ENTER key
toggles between T/C type with temperature unit information and % of range.
INCREMENT (+) Group Keys
The three keys beneath this symbol allow the user to scroll through edit
selections when EDIT icon is lit. The keys are also used to increment numeric
values. For this function, the narrow band signifies fine adjustment, the
medium band signifies medium adjustment, and the wide band signifies coarse
