Section 1 Introduction
The product is dry bath with advanced microprocessor control, which can be widely applied to sample reservation, enzyme reservation and reaction, DNA amplification, electrophoresis degeneration and serum coagulation, etc. Useful for variety of applications in molecular biology and histology as well as clinical, environmental & industrial settings, including restriction digests, denaturing DNA, BUN, melting agar, coagulation studies, hybridization and Hot Start thermo-cycled reaction. The dry baths feature a broad temperature range, up to 150°C, and excellent uniformity. A microprocessor regulates the high wattage heater to provide precise, accurate control and rapid heating. The Aluminum block chamber ensures an even transfer of heat from the heating element to the block. Temperature is easily set using arrow keys while the value is shown on the large display. The user calibration function allows for easy calibration to in-house standards when required. Interchangeable blocks are available to accommodate a wide variety of tubes, plates and slides. Solid blocks are also available for custom machining. Each dry bath is supplied with a block lifter that enables the user to exchange blocks easily, even when the block is hot.
The characteristics of the product are as follows:
Large block 96x96x49mm Precise microprocessor control Broad temp. range, to 150°C (Optional: up to 250°C) Large digital controller with dual display User friendly calibration Rapid temperature increasing rate Optional: RS-232 communication.

Section 2 Safety
During operation, maintenance and repair of this instrument, the following basic safety notes should be observed. In case of failure to follow these instructions, the warnings or notes indicated herein, the basic protection provided by the instrument, its safety criteria of design and manufacture, and its predicted use range would be impaired. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. MRC is not responsible for any injury as a result of the user’s failure to observe the following requirements.
Caution This instrument is for indoor use.
a) The ground connection
To avoid the electric shock, the input power line must be reliably grounded. The instrument is equipped with the three­pin plug that has the third pin (the pin connects the ground), therefore, the plug should be used with the grounded power socket only. This is a kind of safety device. If the plug cannot be plugged into the power socket.
b) Servicing and Replacement of Parts
The operator should not take apart the instrument without permission. Only qualified professionals are allowed to replace elements or adjust components inside the instrument. Replacement of components while unit is connected to power and/or turned on is prohibited.
c) Observe voltage/power requirements
Before the instrument is connected with the AC power source, the voltage of the power source should be the same with the required voltage of the instrument (a deviation of 10% is allowed). The rated load of the power socket should not be lower than the requirements of the instrument.
3, Hagavish st. Israel 58817 Tel: 972 3 5595252, Fax: 972 3 5594529
com.mrclab@mrc
d) The power cord
The instrument should use the power line cord attached to it. If the power line is destroyed, it must be replaced but not be repaired. The replacement should be carried out with the power line of the same type and same specification. No items should be put on the power cord when the instrument is in operation.
e) Connecting and disconnecting from to power source
The user should hold the plug to remove from power source. When connecting the plug, user should make sure it has been fully plugged in; when removing the plug, do not pull the power line forcefully.
f) Placement of the instrument
This instrument should be fixed in a low RH and low dust place away from water source (e.g. sink or water pipeline) and the room should be well ventilated, and free of corrosive gas or interference of strong magnetic field. The instrument should not be placed in a wet or dusty location. the openings on this instrument are for ventilation circulation and in order to avoid over-heat of the instrument body they should not be blocked or covered. When a single set of instrument is used, the interval between ventilation opening before and after the instrument and its nearest object should not be less than 25cm. Also, don’t use the instrument on loose or soft surface, or the air inlet of instrument bottom might be blocked. Excessive temperature will impair performance or result in failure of instrument. This instrument should not be used in location subjected to direct sun light. The instrument should be kept away from hot gas, oven and all other heat sources. If the instrument is to be stored for a long time, the power plug should be withdrawn and the instrument covered with soft cloth or plastic film to avoid entrance of dust. The product is powered by connecting the mains plug to a standard socket­outlet. Always place the product in such a way that it is easy for the operator to disconnect the product from the mains supply.

g) Explanation of symbols
Attention, read user manual before use.
Warning! There is a yellow sign of “CAUTION: HOT SURFACE! ATTENTION: SURFACE HOT” on the instrument. The block should not be touched with any part of the body when the instrument is operating in a high temperature state or just finished operation to avoid burns!
Caution In any of the following cases, immediately turn off the power supply, withdraw the power plug from the power socket, contact the supplier for service:
Liquid drops into the inside of the instrument. The instrument is rained on or water is spilled on it. The instrument works abnormally, especially if generating
an abnormal sound or odor.
The instrument is dropped or its casing is damaged. The function of instrument obviously changes

Section 6 Operation
The chapter introduces the display window and the operation of buttons of the dry bath with constant temperature.
Examination Before Start-Up
Confirm the following before inserting the plug into the power socket.
1. Ensure the power source is in accordance with the voltage
requirement of the instrument (refer to Features section for voltage requirements).
2. Make sure the plug has been fully plugged into the power
socket.
3. Ensure the power line has been reliably grounded.
Caution If the display of the instrument is abnormal after startup, turn off the power source immediately and contact the supplier.
Start-Up
Press the power switch and the instrument will power on. All indicator lights will be turned on. About 3~5 seconds later, temperature display window will show the real-time temperature. All indicator lights will be turned off.
Set the Temperature Value
The setting temperature range is: 5°C Above ambient to 150°C. Press “
” or “” to increase or decrease the temperature value, the
“OUT” indicator will be turned on or flashing, when the instrument temperature is stabilized, the “OUT” indicator will flash Intermittently
Caution DO NOT change any parameters in the controller apart from the temperature setpoint (SV)

Autotuning (AT)
Temperature control using digital PID controllers have automatic auto-tune functions. During the auto-tune period the PID controller controls the power to the process and measures the rate of change, overshoot and response time of the plant. This is often based on the Zeigler-Nichols method of calculating controller term values. Once the auto-tune period is completed the P, I, D values are stored and used by the PID controller. Use AT function to automatically calculate and set the optimize PID value for your system
DO NOT touch the block or the temperature controller
during autotuning process.
Temperature Offsetting (OFFSET)
The temperature shown on the Actual Temperature Display is measured by a temperature sensor inside the unit. However, this temperature can be different from the temperature of your own thermometer which you may use as a standard for your specific applications. If needed, you can offset such temperature differences at 0.1°C interval
NOTICE
If, for example, the actual temperature in the block is 100°C but the displayed temperature is 98°C, you can match the displayed temperature with the actual temperature of the unit by selecting the offset value of +2°C
