1.INTRODUCTION
The Novus Calibrators series DC80 are portable instruments designed to meet the
user needs for measuring and simulating signals such as voltage, current,
resistance, thermocouples and RTDs. The available options depend on the
particular model. They are:
•DC80T, for Thermocouples and mV
•DC80R, for RTDs and resistance
•DC80L, for linear mV, V and mA (provides internal power supply for
powering 2-wire transmitters)

2.SAFETY INFORMATION
To avoid possible electric shock or personal injury:
•Use the Calibrator only as specified in this manual, or the protection provided
by the Calibrator might be impaired.
•Do not apply more than the rated voltage between the terminals, as marked on
the Calibrator, or between any terminal to earth.
•Make sure the battery door is closed and latched before operating the
calibrator.
•Remove test leads from the calibrator before opening the battery door.
•Inspect the Calibrator before using it. Do not use the Calibrator if it appears
damaged.
•Do not operate the calibrator around explosive gas, vapor, or dust.
To avoid possible damage the calibrator or system, make sure to use the right
connector and select the appropriate range before using the instrument for
measurement or simulation.

3.3. MODEL DC80T OPERATING INSTRUCTIONS
In thermocouple temperature simulation the calibrator generates the voltage as an
actual thermocouple, considering both the simulated temperature (hot joint) and
connection temperature (cold joint). To ensure stated accuracy the user must use
a connection cable between calibrator and calibrated device with the same
thermoelectric properties of the selected thermocouple (extension or
compensation cable).
A K type extension cable (yellow connector) is supplied with the calibrator and
should only be used for K type calibration for maximum accuracy.
Make sure that the appropriate cable with the correct polarity is being used to
avoid large calibration errors.

5.MODEL DC80L
The DC80L is the calibrator model for measuring and simulating V, mV and mA
signals. The DC80L is capable of measuring and generating 0 to 24 mA DC
current signals and voltages up to 15 V DC. Simultaneous measurement and
signal simulation is not provided.
Current measurements options are:
-With use of external power supply provided by the system. In this case, the
calibrator is placed in series to measure the loop current (signal of a 2-wire
transmitter, for example).
-The calibrator provides the power to the loop. This option makes use of the
DC80L built-in power supply. This configuration applies to measurements of
standalone 4-20 mA transmitters (sink type transmitters).
Current simulation possibilities are:
-The calibrator sources the current to the target instrument.
-The calibrator simulates (behaves as) a 2-wire transmitter.
The following tables show the DC80L specifications functions and ranges, based
on a one year calibration period, at ambient temperatures ranging from +18 °C to
+28 °C. “Counts” means units of the least significant digit.

5.3. PROTECTION
The MODEL DC80L calibrator uses two protection fuses, rated 125 mA / 250 V,
internally connected in series with the current terminals (2) and (4).
To avoid personal injury or damage to the calibrator, use only 125 mA / 250 V fast
fuses.
Notes on fuses:
-Fuse 1 is probably blown out when the display flashes the message OL while
in Voltage output mode with the leads removed from the calibrator.
-Fuse 2 is probably blown out if the calibrator reads 0.000 in mA input mode,
even under the presence of a current input signal
