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.
Model: 8801 Single Input Model: 8803 Dual Input BUTTON DESCRIPTION ON/OFF o C/ o F HOLD MAX HLD T1.T2 T1-T2 Power ON and Power OFF Unit selectable oC or oF Freeze the current reading Record Maximum reading T1 temperature or T2 temperature or differential temperature between T1& T2 OPERATION Plug thermocouple in the meter as shown Figure 1 or 2. Press ON/OFF button to start. Fig. 3 shows the normal display when either T1 or T2 thermocouple is pluged in. + T1 + #8801 Fig.1 T2 oC #8803 + Fig.
SELECTING oC / oF Press oC/oF button to select oC or oF. The display will show "oC" or "oF" to indicate which scale has been selected. See Fig.3 and Fig.5 ,an example to toggle unit from oC to oF. NO-SLEEP MODE DISABLEMENT Press ON/OFF button to turn off the meter. The meter will auto shut off if no button is pressed within 20 minutes. To disable auto power off, press HOLD and ON/OFF key simultaneously, until an "n" appears on the screen (See Fig.
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 (---) (Fig.
To release the MAX HOLD function, press the MAX HLD button again. When the MAX function is set, the meter is recording and will update the maximum measurement display with a new maximum reading . oF Fig.10 MAX HOLD HOLD FUNCTION Press the HOLD button to apply data HOLD Function. The "HOLD" appears on the display then(Fig.11). When HOLD function is set, the meter holds the present readings and stops all further measurement. To release HOLD function ,press the HOLD button again.
