TROUBLESHOOTING
1) Unit Does Not Turn On: Batteries are installed
incorrectly or dead. Check batteries are installed
according to picture on rear label. Replace batteries.
2) Display Shows “Prob”:
Probe is broken (Open
thermocouple. See “Test for Broken Probe”
below).
3) Test for Broken Probe: Pull the probe connector out
partially to expose the blade contacts. Place a metal
paper clip across connector blades to short contacts.
If instrument displays temperature, the probe is
broken. Replace Probe.
4) Battery Icon Appears on Display:
Low battery.
Replace batteries.
5) Display Shows “bAtt” and Instrument Shuts Off:
Replace batteries.
6) Display Shows “LO” or “HI”:
Temperature measured
is outside measurement range of instrument.

PROBE CONNECTORS LOCATED INSIDE COLD ENVIRONMENTS
It is recommended that the probe connector is located outside of any cold environments to
avoid any inaccuracies.
If the probe cord is not long enough to fit outside of the cooler or freezer, it can be left in that
environment during the wait time of 3 to 5 minutes. However, if the probe connector is exposed
to these cold environments, and then plugged into the thermocouple instrument, it needs to
acclimate for approximately 4 minutes. This will compensate for the temperature difference
between the probe connector and the instrument to avoid inaccurate readings.
To avoid taking innaccurate readings, do not leave the thermocouple instrument in these
environments longer than the recommended times explained above.
Probe replacement is no longer necessary as long as the calibration process yields an
accuracy within the stated range, and the calibration process is performed within the actual
in-use environment. If any calibration results demonstrate out of tolerance conditions for
a TempTrak ® transmitter or probe, the equipment will need to be replaced (refer to current
price schedule). For further information contact your local TempTrak sales representative.
SysCal ™ CALIBRATION PROCESS
The Syscal calibration process was designed to monitor the accuracy of a previously
installed TempTrak® transmitter and its modified* Solid Simulator Probe. This process will
be used with the transmitter and solid simulator probe connected, measured as a unit, and
in place within the use environment.
Calibration of the transmitter and solid simulator is achieved by comparing the documented
readings from the transmitter and solid simulator with the reading from the SysCal™
35025 Thermocouple and the 50219-K Probe. This reading is referred to as the reference
standard.
The Total System Accuracy (TSA) of SysCal is ±0.5°F (±0.3°C). A certificate of calibration
from an ISO 17025 accredited laboratory is also supplied. This accuracy will provide a Test
Uncertainty Ratio (TUR) of 4:1 when used as the reference standard for the TempTrak
transmitter and Solid Product Simulator.
*The modified solid simulator incorporates a secondary hole in the opposite end from where the thermistor sensor is inserted
into the solid simulator. This secondary hole is used to place an insertion probe in the vicinity of the simulator’s thermistor
sensor.
