MC-1000
1. Introduction
The MC1000 is designed to be a versatile, easy
to use multi-function calibrator with a simple
user interface. The following instructions will
allow the user to begin simple calibration tasks
by learning the basic operation of the keys and
their functions.

The following definitions apply to the terms
“Warning” and “Caution”.
• “Warning” identifies conditions and actions
that may pose hazards to the user.
• “Caution” identifies conditions and actions
that may damage the instrument being used.
Use the calibrator only as specified in this man-
ual, otherwise injury and damage to the calibra-
tor may occur.
Warning
To avoid possible electric shock or
personal injury:
• Do not apply more than the rated voltage.
See specifications for supported ranges.
• Follow all equipment safety procedures.
• Never touch the probe to a voltage source
when the test leads are plugged into the cur-
rent terminals.
• Do not use the calibrator if it is damaged.
Before you use the calibrator, inspect the
case. Look for cracks or missing plastic. Pay
particular attention to the insulation surround-
ing the connectors.
• Select the proper function and range for your
measurement.
• Make sure the battery cover is closed and
latched before you operate the calibrator.

• Remove test leads from the calibrator before
you open the battery door.
• Inspect the test leads for damaged insulation
or exposed metal. Check test leads continuity.
Replace damaged test leads before you use
the calibrator.
• When using the probes, keep your fingers
away from the probe contacts. Keep your fin-
gers behind the finger guards on the probes.
• Connect the common test lead before you
connect the live test lead. When you discon-
nect test leads, disconnect the live test lead
first.
• Do not use the calibrator if it operates abnor-
mally. Protection may be impaired. When in
doubt, have the calibrator serviced.
• Do not operate the calibrator around explo-
sive gas, vapor, or dust.
• When using a pressure module, make sure
the process pressure line is shut off and
depressurized before you connect it or dis-
connect it from the pressure module.
• Disconnect test leads before changing to
another measure or source function.
• When servicing the calibrator, use only speci-
fied replacement parts.
• To avoid false readings, which could lead to
possible electric shock or personal injury,
replace the battery as soon as the battery
indicator appears.
• To avoid a violent release of pressure in a
pressurized system, shut off the valve and
slowly bleed off the pressure before you
attach the pressure module to the pressure
line.

Caution
To avoid possible damage to calibrator or
to equipment under test:
• Disconnect the power and discharge all high-
voltage capacitors before testing resistance
or continuity.
• Use the proper jacks, function, and range for
your measurement or sourcing application.
• To avoid mechanically damaging the pressure
module, never apply more than 10 ft-lb. of
torque between the pressure module fittings,
or between the fittings an the body of the
module.
• To avoid damaging the pressure module from
overpressure, never apply pressure above the
rated maximum printed on the module.
• To avoid damaging the pressure module from
corrosion, use it only with specified materials.
Refer to the pressure module documentation
for material compatibility.
2. Quick Start Instructions
A. Key Functions
Key Function
Input/Output Toggles the function selected
from measurement mode to
source mode.
V/mA/Hz Selects between volts, mil-
liamps, and frequency modes
TC/RTD Selects between temperature
modes either T/C or RTD.
Ohms and mV ranges are also
included in these functions.
Ranges/Units This key toggles through all
the ranges for a chosen func-
tion. Example: If T/C mode is
selected the Range key tog-
gles through the ranges J, K,
T, E, etc.
0-9 keys These keys allow a user to
enter an output value.
Example: to output 20 mA
select mA output and Press
the “2” key then the “0” key
followed by the “ENTER” key.
Arrow ↑↓ These keys allow small
changes to be made to an out-
put value. Press either the up
or the down arrow key to set
the value as desired.
CE The clear entry key allows the
user to clear a value before the
enter key is pressed.
Shift This key has a blue text color
6
and acts as a second function
key to all keys that have an
associated second function.
Features such as setpoints,
°F/°C, backlight and external
pressure module activation all
use the Shift key.
B. Setpoints
1. Storing Setpoints
The setpoint mode allows up to 9 set-
points to be stored in non-volitile memo-
ry for each range. The procedure is as
follows:
a. Set the output to the desired value.
b. Press shift followed by the “SET” key.
c. Choose the desired setpoint storage
location by pressing a key (1-9).
d. Enter a new value and repeat steps 1
thru 3 as needed, up to 9 setpoints for
each range can be stored.
2. Recalling Setpoints
a. To recall a setpoint, press shift fol-
lowed by the”SPT” key.
b. You will be prompted to enter the
number of the desired setpoint loca-
tion stored previously.
c. Press the desired location number and
the unit will go to that output.
3. Automated Stepping
The MC1000 can auto-step through
some or all of the stored setpoints for a
given range. The procedure is as follows:
a. Press “Shift” followed by auto.
b. “Auto SPT ?” will appear. Enter the
7
ending setpoint location. Example: if
you have all 9 setpoints stored but
only want to step through the first 3
then enter “3” for this question.
c. The next screen prompts you to enter
the dwell time from 5 to 500 seconds.
Simply enter a number in that range.
Then press the “Enter” key.
d. Auto-step will begin.
e. To exit auto-step press “CE” key or
enter a value.
4. Manual Stepping
The MC1000 can be manually stepped
through all or some of the stored set-
points. The procedure is as follows:
a. Press “Shift” followed by “Man”.
b. Using the arrow keys, toggle up and
down through the stored setpoints.
c. To exit press CE or simply enter a new
output value.
5. Pressure Module Interface
The MC1000 has the capability to inter-
face with a family of pressure modules
available from Martel. The procedure is
as follows:
a. Connect the pressure module to the
15 pin “D” connector on top of the
MC1000.
b. Press “Shift” followed by the “ ”
key.
c. Always zero the pressure module
before starting a calibration. Press
“Shift” followed by the “Zero” key.
Note: More detailed information can be found with
the instructions packaged with each module.
