I. Introduction:
This instrument is a digital thermometer for use with any K-type thermocouple as temperature
sensor. Temperature indication follows National Bureau of Standards and IEC584
temperature/voltage table for K-type thermocouples. Its internal memory can store up to 16,312
records.(See Note 1 below.) An RS232 interface provides bi-directional communication with a PC.

Note1:
Each time you press the "RECORD" button to start recording data and press it again to stop recording, a
new data set is stored in memory. As many additional data sets as you want may be added into memory
until it is full.
Temperature Coefficient:
For ambient temperatures from 0°C ~ 18°C and 28°C
~ 50°C, for each °C ambient below 18°C or above
28°C add the following tolerance into the accuracy
spec.
0.01% of reading + 0.03°C
(0.01% of reading + 0.06°F )
