2.Operation Method

Preparation

From mounting of the aluminum block to operation start

1.Mounting the aluminum block

Hand grip for aluminum block

2.Connecting the power cord

3.Installing the sample

4.Turning ON power supply

5.Starting operation

Use the dedicated aluminum block available separately.

The use of an attached dedicated hand grip will prove convenient for mounting/removal of the aluminum block.

Caution Possible hazard of burn. Use the hand grip when the aluminum block is sufficiently cooled.

Do not raise the temperature while keeping the hand grip left attached.

If necessary, a bar thermometer may be inserted into a thermometer hole (used also for attaching the hand grip) of the aluminum block.

(Use the thermometer of maximum 200 or more. Since the bar thermometer is not attached, obtain it separately.)

Bar thermometer

Connect the power cord to an appropriate receptacle firmly. The receptacle to be connected must be of a 100V 15A type.

To maintain the temperature accuracy, use a sample container appropriate in size to the sample installation hole of the aluminum block.

Turn ON the POWER switch of the main body and set the desired temperature using▲▼ keys of the operation panel.

Press the START/STOP key of the operation panel for one second, and the operation begins.

Aluminum block, which is available separately

The following types of aluminum blocks are available for HF100/HF200. Be sure to use the aluminum block dedicated to the product concerned.

Specify the product code No. when purchasing.

2. How to operate the unit

List of operation modes and functions

The operation functions of the product are as follows.

Nomenclature

 

Description

1

Fixed-value operation

Continuous operation mode

P.6

 

 

 

 

Press the

START/STOP

key for one second after temperature

 

 

 

 

 

setting, and the continuous operation begins. Pressing the

 

 

 

 

 

START/STOP

key again for one second causes stop of

 

 

 

 

 

operation.

Quick

auto-stop

 

Causes activation of the timer halfway of fixed-value

P.8

 

operation

 

 

operation, then automatic operation stop after the set period.

 

 

 

 

 

This function is used “to set the automatic stop after the set

 

 

 

 

 

time”, “to set, in the course of operation, the automatic stop in

 

 

 

 

 

several hours.”

 

3

Auto-stop operation

Used “to set the automatic stop at the specified time” before

P.11

 

 

 

 

starting the operation. In the auto-stop mode, the timer starts

 

 

 

 

 

counting when the set temperature is reached.

 

4

Auto-start operation

Used to start the automatic operation in several hours, that is,

P.15

 

 

 

 

“to set the automatic start at the specified time.”

 

The temperature and timer’s set time can be changed during operation.

Cautions for the auto-stop operation

The timer does not start counting till the bath temperature reaches the set level.

When the set temperature is below the bath temperature, the timer does not start counting till the bath temperature drops below the set temperature.

The operation functions of sub-menu of the product are as follows.

 

 

Keep pressing the

 

key for four seconds. The mode changes to the sub-menu mode.

Calibration

offset

 

The calibration offset function is to compensate for

any

P.21

 

function

 

 

 

difference occurring between the target bath temperature and

 

 

 

 

 

 

controller control temperature (sensor temperature).

 

 

 

 

 

 

 

Compensation can be made either to the positive or negative

 

 

 

 

 

 

side over the entire temperature range of the system.

Over-temperature

The automatic over-temperature preventive function is

preventive function

incorporated.

 

 

 

When the bath temperature rises excessively along with the

 

 

 

set temperature of the device, this is set to activate

 

 

 

automatically at +12 .

 

 

 

Stop operation when this function is activated. The Alarm

 

 

 

lamp flashes. To cancel, turn ON the power switch newly

 

 

 

again (manual reset).
