1 Safety Instructions

Warning!

•Read the operating instructions carefully

before use.

•Ensure that only trained staff work with the

instrument.

Risk of burn!

•Caution when touch the housing parts and

the hotplate which can reach temperature of

340°C.

•Pay attention to the residual heat after

switching off.

Protective ground contact！

•Make sure that the electrical socket is

grounded (protective ground contact) before

use.

•When operating wear personal safety protection to avoid

the risk from:

-Splashing and evaporation of liquids

-Release of toxic or combustible gases

•Use the instrument in a spacious area on a stable, clean,

non-slip, dry and fireproof surface. Do not operate the

instrument in explosive atmospheres, with hazardous

substances or around water.

•Gradually increase the speed, reduce the speed if:

-Stirring bar breaks away due to high speed

-The instrument is not running smoothly, or the container

is not centered on the plate

•Temperature must always be set to at least 50C lower than

the flash point of the media used.

•Be aware of hazards due to:

-Flammable materials or media with a low boili ng

temperature

-Overfilling of media

-Unsafe container

•Process pathogenic materials only in closed vessels.

•If the case of the stirrer bar is PTFE, please note：

-Elemental fluorine, three fluoride and alkali metals will

corrode the PTFE and Halogen alkanes make it expand at

room temperature

-Molten alkali，alkaline earth metals or their solution, as

well as the powder in second and third ethnic of the

Periodic Table of Elements will have chemical reacti on

with PTFE when temperature reaches 300 ~ 400C .

•Check the instrument and accessories prior to each use.

Do not use damaged components. Safe operation is only

guaranteed with the accessories listed in the “Accessories”

section. Accessories must be securely attached to the device

and must be removed when not in use. Always disconnect

the power before fitting accessories.

•When using the external temperature sensor, the tip of the

measuring sensor must be at least 5-10mm from vessel’s

bottom and wall.

•The instrument can only be fully disconnected from the

main power supply by turning off the main or disconnecting

t he plug.

•The voltage stated on the label must correspond to the

main power supply.

•Ensure that the main power supply cable does not touch

the hotplate. Do not cover the device.

•The instrument must only be operated by adults.

•Keep away from high magnetic fields.

2 Proper Use

The instrument is designed for mixing and/or heating

liquids in laboratories:

•Do not use more than 2000 meters above sea level

•Temperature between 0℃and 40℃

•Installation Type: Product is designed to connect the

indoor outlet, where voltage fluctuation is not more

than ±10% compared with normal.

•Observe the minimum distances between multiple

units, and distances to the rear wall and above the

assembly (min. 100 mm).

This device is not suitable for using in residential areas or

other constraints mentioned in Chapter 1.

higher priority. If in this case speed is changed via

the stirring knob, it display

reverts to temperature after 5 seconds.

5 Trial Run

•Make sure the required operated voltage and power

supply voltage match.

•Ensure the socket is properly grounded.

•Plug in the power cable, ensure the power is on and

begin initializing.

•Add the medium into the vessel with an appropriate

stirring bar.

•Place vessel on the work plate.

•Set the target stirring speed and begin.

•Observe the stirring bar and LCD display.

•Set the target temperature and start heating.

•Observe the real temperature on LCD display.

•Set the timer.

•Timer ends, the heating function stops.

•Stops stirrer function.

If these operations above are normal, the device is ready to

op erate. If these operations are not normal, the device may

be damaged during transportation, please contact

manufacturer/supplier for technical support.

Warning !

Do not remove the vessel when the instrument is

operating.。

6 Function: Heating

The device is controlled by digital temperature control

technology, which has two separate safety circuits. The

hotplate is kept at a constant temperature by a digital

control circuit. The hotplate temperature can also be

controlled from a separate, adjustable safety circuit. The

two temperature sensors (PT1000) internal for temperature

control are built into the hotplate. The single external

PT1000 can control the temperature of sample.

•Plug in the external PT1000.

•Set the temperature via rotating the temperature

control knob slowly to the target value, press

parameter set knob and switch on the heating function.

•When the heating function is switched on, the LED

“Heat” will light up and the LCD will display the

actual temperature.

•The set temperature will be displayed on the

right-hand side of the LCD as well as Temp and °C

characters.

•The heating function is switched on or off by pushing

heating knob.

Instrument is turned on for the setting zone temperature

setting when the last shutdown temperature, the common

case, set the heating temperature display the actual

temperature may have the following differences:

-Hotplate center and outer edge.

-The sample container and the container.

In order to ensure the accuracy of the liquid temperature

inside the container, please use the PT1000 external

temperature sensor.

6.1 Working with the PT1000 external

temperature sensor

Figure 6

The PT1000 external temperature sensor is the

manufacturer’s optional accessory. If the sensor is plugged

in, “Probe” will be shown on the digital display to indicate

the sensor is operating. The setting value of external

temperature sensors and actual temperature are displayed.

The safety circuit controls hotplate temperature.

Comparing with the temperature control of the hotplate, the

external temperature sensor can control the medium’s

temperature more precisely. The external temperature

sensor must be put in sample container, if detect anomalies,

heating will automatically shut down. Please do the

following at this time:

•Turn off the power

•Ensure the external temperature sensor is positioned

sample container correctly

•Turn on the power, set the target temperature and

switch on the heating function

•If the unit is still not functioning correctly, please

contact manufacturer/supplier

6.2 Residual heat warning（HOT）

In order to help prevent the risk of burns from the hotplate,

this instrument has a residual heat warning function. When

the heating function is switched off (and the power cord is

still plugged in) and the heating plate temperature is still

above 50°C, “Hot” will flash to warn that it is unsafe to

touch.. When the hotplate temperature drops to below 50°C,

the display will automatically switch off. To completely
