IV. Name of parts and function
LCD: Display readings, polarity ”-”, low battery” ” unit
(℃, ℉)
Power switch: ON/OFF switching.
Data Hold: apply to the situation uneasy to read display, Date
hold must be canceled before next measurement.
℃ switch: For measurements under ℃ unit.
°F switch: For measurements under °F unit.
Range selection switch: For selecting various ranges
(resolutions)
Temp measuring socket: input conjunction socket for
measuring.
V. Inspection before using
Make sure battery is connected well. Battery needs to be
replaced while LCD displays” ”.
Make sure all function switch are in proper position. (Data
hold in off status “HOLD” should not appear on LCD)
Make sure plug of temp probe is plugged in socket well
(terminal “+” to “+” “-“ to “-“)
VI. Measurement
Select unit (℃ °F) by function switch.
Plug the plug of temp. probe to the temp socket.
Apply sensor (thermocouple) to the measured place.

Note:
1. To secure accurate reading, please insert probe to the
measured article about 15~20 times of O.D. of probe, while
measuring internal temp. or liquid.(see Fig. 5).
2.While measuring surface temp, touch the surface with tip
of temp. Probe closely. (See Fig.6)
3.Calibration point and sequence:
VR1 for 0°C,VR2 for 0°F,VR3 for 165°F, VR4 for 952°F, VR 5
for 511°C.
4.The OFFSET controls are set at the factory to al low for
the variations found in standard thermocouples. By
adjusting the OFFSET controls, your con optimizes
measurement accuracy for a particular thermocouple at a
particular temperature.
Adjusting for Accurate Measurements
1. Connect the thermocouple to the input connector
and turn the thermometer ON, then press the 0.1°
key to select the high display resolution.
2. Place the thermocouple in a known, stable
temperature environment at or neat the temperature
you with to measure, and allow the readings to
stabilize.
3. Slowly adjust the OFFSET control so that the
thermometer reading matches the temperature of the
known environment. Leave sufficient time between
adjustments to allow for measurement lag.
4. The calibration of the thermometer-thermocouple
combination is now optimized for measurements
near the temperature measured in step 2.
Resetting the OFFSET Control
To return the OFFSET Control to their factory setting
without having to recalibrate the thermometer, perform the
following procedure:
1. Connect a thermocouple that is in good working
order to the input that is to be adjusted.
2. Place the thermocouple in an ice- water bath and
allow the readings to stabilize.
3. Slowly adjust the OFFSET control until the
thermometer reads 0
℃ (32) ℉.
VII. Maintenance
4. Take off battery in long time storage.
5. Do not operate the meter under the environment with
explosive gas (material), combustible gas (material)
steam or filled with dust.
6. YF-160A is suitable for K (CA) type thermocouple
only.
7. Avoid using in environments, which change fast. Do
not store in high temp high humidity and strong
violation.
8. Thermocouple may be oxidized reduced eroded
polluted, steamed, diffused or affected by other
metallic factors.
9. Move dust, oil, and coal to keep temp. probe clear
and avoid tolerance. Replace the probe while being
eroded
10. Replace battery (as illustrated below)
11. Insert a “-” screwdriver to the hole of battery cover.
12. Insert the screwdriver deeper by pressing it down.
1.) Push the screwdriver forward to take off battery cover.
