Operation Method

Other Functions

Use calibration offset function

Calibration offset is a function which corrects the difference between the temperature in furnace and that of controller (sensor temperature) if arises. The function parallel corrects the difference either to the plus or minus side within the whole temperature range of unit. The function can be set or cancelled by the SUBMENU key.

Corrected temp. to plus side

Current temperature

Corrected temp. to minus side

① Start operation with the target setting temperature. Check the temperature in furnace (temperature of sample) with a thermograph after it is stabilized.

②

Check the difference between the setting temperature and that in furnace

(temperature of sample).

③

Press the SUBMENU key. Select the character "cAL", which indicates the calibration offset, using the "▲▼", and then press the ENTER key.

④

Input the difference using the "▲▼" and then press the ENTER key.

This completes the setting.

The setting range of offset correction temperature is +99℃ to plus side and

-99℃ to minus side respectively.

When it is set to the minus side, the temperature on the measurement temperature display screen falls by the setting temperature, while the temperature on furnace rises.

When it is set to the minus side, the temperature on the measurement temperature display screen rises by the setting temperature, while the temperature on furnace falls.

The unit has two-point correction function, which performs offset between low-temperature zone and high-temperature zone. Please consult our local branch office when carrying out validation of temperature controller.

Use lock function

This function locks the operation status previously set. The function can be set or cancelled by the

SUBMENU key.

①

Press the SUBMENU key. Select the character" "Lock", which indicates the lock of setting value, using the "▲▼", and then press the ENTER key.

②

The setting temperature screen displays "oFF". The setting value is locked when it is turned to "oｎ" using the "▲".

③

Press the SUBMENU key again to cancel the lock. Select the character"

"Lock", which indicates the lock of setting value, using the "▲▼", and then press the ENTER key. Select "oFF" with the "▼" and then press the ENTER key to cancel the function.

All keys other than the START/STOP and SUBMENU keys are lock when the lock function is on.

Do not put anything on this unit

Do not put anything on this unit. It will cause injury if fall.

During a thunder storm

During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and the main power. If this procedure is not followed, fire or electrical shock may be caused.

Do not touch high-temperature parts

Some parts of this unit may become hot during and just after operation. It may cause burns.

Sample loading

Overload of samples may cause the malfunction of the temperature control. Do not use this unit with too much samples. Leave a certain space between samples.

Return after power failure

When power is supplied after a power failure, the device automatically starts operation again with the same state as just before the power failure. It is danger that the device starts unattached operation after a power failure. We recommend for you to turn off the switch of this unit if a power failure occurs during operation.
