Be sure that the screw is designed not to drop from the lid.
4. Exchange the batteries according to the description in the battery box.
5. Confirm that the black packing seal is firmly put into the groove, then tighten the
screw until the screw head comes under the body surface.
Maximum and minimum temperatures are initialized after replacing batteries.
Cautions Related to Batteries
Do not dispose of batteries in a fire, or it may explode to hurt you.
For environmental conservation purposes, dispose of batteries in compliance with
local rules and regulations.
Keep batteries out of the reach of children. If they are swallowed accidentally,
consult a doctor immediately.
If battery fluid leaks out, wipe it away immediately without touching it directly.
Remove the battery if not used for a long period, or it may lead to fluid leakage and
malfunction.
Do not use rechargeable batteries, because the sealed structure of PC-3710 can
accumulate gas leaked from the battery to cause a fire or explosion.
Attach the battery lid firmly to the body with the packing seal put into the groove,
and secure the screw. Otherwise, the device may fail to be waterproof and result
in malfunction, short-circuit, battery leakage, extreme heat, or explosion.
How to Use
1. Refer to “Replacement of Batteries” to open the battery lid and remove an
insulation sheet.
The measurement begins immediately, and current temperatures of the internal
sensor (IN) and the external probe (OUT) are shown first. After then two
temperatures are alternately measured every 5 seconds. Each of them is
updated per 10 seconds.
2. Install the device using either the frame stand, hanging hook, or the magnets
embedded in the back. Carefully check if it is placed safely.
3. Let the device adapt to the ambient environment for more than 30 minutes.
Internal Sensor (IN)
The temperature of the internal sensor is displayed with a sign of “IN” in the lower
row. Connector cap must be closed.
As it cannot be used in the environment where temperature falls below −5°C
or exceeds 50°C, place only the external probe in the said environment and
keep the body outside of it in such case.
External Probe (OUT)
The temperature of the external probe is displayed with an indicator of “OUT” in the
upper row when the probe is firmly inserted to the connector. Hooking the clasp
attached to the cable on somewhere helps the probe get fixated.
Close the sensor cap securely if you do not use the external probe.
Cautions When in Use
The device accepts water splashes, but it does not mean that the body and the
probe can be submerged in water.
Do not pull the probe strongly, or it may break.
The sensor part made of stainless steel may get deteriorated when it contacts with
corrosive liquid. Do not measure temperature of such liquid.
The magnet may not work well depending on a surface condition where it takes
place.
Measurement error can be enlarged when your hand touches the cable.
A sign of “HHH” or “LLL” is indicated when the temperature is out of range.
For better management, it is recommended to compare the measured value with
that of a standard thermometer to check accuracy once in a year. We offer
traceable calibration service.
Max/Min Temperatures
PC-3710 logs the maximum (MAX) and minimum (MIN) temperatures. Each press
of the key in the front makes the device show MAX, MIN, and current temperature
in this order.
Their logging is initialized when the key is press for 3 seconds, or the battery is
replaced.
