W
WARNIN
G
This instrument is designed to accept low
level signals supplied by standard 100 Ω
RTDs. Under no circumstances should the
input voltage exceed the specified 10 v rms.
1. Do not use or store this instrument in
microwave ovens or any abnormally hot
or cold areas.
2. Weak batteries should not be left in the
instrument. Dead batteries can leak and
cause damage to unit.

Voltages present at the RTD may also be
present at the battery terminals. Always
disconnect the RTD when changing
batteries.
Weak batteries should not be left in the
instrument. Dead batteries can leak and
cause damage to unit.
The typical battery life is about 700 hours.
Selected settings are stored in memory and
will remain in memory even after power
is turned off, or while batteries are being
replaced.
1. Before
changing batter y , tur n
instrume
nt off and disconnect probe .
2.
Loosen screw and lift batter y cover off
the
back of case.
3.
Remove the t hree AA batteries.
4. Insert three
new batteri es observing

5. INSERTING AND REMOVING
OPTIONAL RUBBER ARMOUR
Figure 1: Removing Optional Rubber Armour
1. To insert thermometer into the optional
rubber armor, slide in from the top of
meter before pushing the bottom edges
of meter down to set it into position. Lift
up the stand at the back of meter for
bench top applications if necessary.
2. To remove thermometer from armor,
push out from the bottom edges of
meter until it is completely out of boot.

6. ASSEMBLING OPTIONAL
HANDSFREE ACCESORIES
You can use the optional magnets and strap
in the Hands Free Kit accessories for hands-
free operations.
Figure 2: Hands Free Kit

7. CONNECTING AN RTD PROBE
Use the correct 100 ΩRTD (alpha =
0.003850) for your instrument. Using an
incorrect probe type will result in erroneous
readings. Insert the 3-pin plug into the
mating connector on the top of the
instrument.

10. MEASUREMENT MODE
Press the on/off key. The thermometer
performs a self-test and all display digits and
indicators should remain on for
approximately two seconds before the meter
enters measurement mode.
If a probe is not connected or if the probe is
defective, the display will indicate “OPEN”.

Figure 6: Display when no probe is detected
For optimum instrument accuracy, allow one
minute for ambient temperature stabilization.
If the unit has been stored at an extreme
ambient condition, more time will be needed.
A STABLE indicator appears at the top right
corner of the display when reading is
continuously stable for 5 seconds.
To freeze reading, press hold. Press hold
key again to release the reading and resume
normal operation.

12. MIN AND MAX FUNCTION
Press the min/max key to toggle between
the minimum and maximum readings. The
minimum and maximum reading function is
ideal for monitoring unattended operations
while continually displaying every
temperature change that occurs. The
minimum and maximum values are sensed
and automatically stored. To exit and clear
the MIN/MAX reading stored, press and hold
the min/max key for 3 seconds.
13. AUTO OFF FUNCTION
The thermometer has a default auto off
function of 17 minutes.
To deactivate this function, press the
min/max key while turning the thermometer
on with the on/off key. “A.OFF no” flashes
to show indicate that the auto off function
has been disabled for that session.

14. CALIBRATION
The CAL function allows single point
calibration of the thermometer at 0°C (32°F)
to compensate for probe offset error. Use
the field calibration feature to improve
thermometer/probe accuracy.
The Temp-16 Precision RTD Thermometer
comes with a calibration lock function to
prevent accidental changes to calibration
settings. A field calibration can only be
performed when the function has been
unlocked. To unlock field calibration, follow
steps 1 through 4 in FIELD CALIBRATION
UNLOCK section.
To calibrate:
1. Pack sensing end of probe in a
container tightly packed with crushed ice
and filled with distilled water. Allow
temperature to stabilize.
2. Press and release the cal key for 3
seconds to enter the calibration mode.
The CAL indicator starts blinking.
Release the cal key.
3. If the measured temperature is from
-5°C to 5°C (23 to 41°F) when the
temperature reading is stable, press the
cal key.
The CAL indicator will stop blinking, and the
reading will be set to 0°C (32°F). The CAL
indicator will remain in display, indicating
that field calibration is now active.
If “Err” is displayed, the displayed reading is
outside the above limits.
NOTE: Press any key (except the cal key)
while in calibration mode to abort
calibration.

15. CLEAR FIELD CALIBRATION
To clear user calibration:
1. Turn the thermometer off.
2. Hold the cal key down while pressing
the on/off key.
3. The measurement mode window
appears without the CAL indicator to
indicate that the user calibration has
been successfully cleared.
16. FIELD CALIBRATION UNLOCK
The calibration unlock feature enables field
calibration operation. To unlock field
calibration:
1. Turn the thermometer off.
2. Hold the cal key and hold key down
simultaneously, then press the on/off
key.
3. The “CAL” indicator appears
momentarily with the version-model
window to indicate that the user-
calibration function has been unlocked
successfully (Figure 10).
