INSTRUCTION MANUAL
K TYPE THERMOMETER
Model: 8801 8803
INTRODUCTION
The 8801 and 8803 are 3 1/2 digit, hand
-held thermometer designed to use Ktype thermocouple as temperature
sensor.
8801 For 1 K-type Thermocouple input
8803 For 2 K-type Thermocouple input
SAFETY
To avoid electrical shock, disconnect
the thermocouple connectors from the
thermometer before removing the
battery cover and do not use this
meter on voltage at the measurement
surface beyond 24V AC or 60V DC.
To avoid damage or burns, do not
apply this meter in microwave ovens.
To ensure lead quality, avoid repeating
sharp bends in the leads as it can
damage the thermocouple leads,
especially near the connector.

Press T1.T2/T1-T2 button to display the
temperature for T1 input. (Fig.8) Press
T1.T2/T1-T2 button again to display the
temperature for T2 input. (Fig.7)
Press T1.T2/T1-T2 button one more time
to display the differential temperature
between the two thermocouples.(Fig.9)
The display will show T1,T2 or T1-T2 in
turns by pressing the same button.
Note:
Model 8801 can only display one
temperature. Only make sure the
thermocouple is plugged at the left side
on the top . No reading but 4 dashes (---
