Features
1. Chamber Temperature Adjustment
It is capable of cultivating the bacteria that prefer from medium temperature to high
temperature.
- Constant temperature environment by microcomputer PID control + air jacket (natural
convection)
- Achieve constant temperature environment with high accuracy that temperature
fluctuation is within ±0.2℃ (set temp. 37℃, center in chamber)
- Temperature setting range: room temperature +5℃~80℃ (ambient temperature 20℃)
2. Alarm and Safety Function
- Temperature alarm: when the temperature deviated ±2.5℃ from set value
(Lamp, Buzzer)
- Overheat Protection: the heater is OFF when the temperature exceeds the upper limit.
- Overcurrent breaker combined power switch
- Key lock switch
- Memory backup: store the settings even after the power supply is OFF
- Self-diagnosis function: display errors and shutdown when any abnormality is detected,
such as sensors, etc.
3. Usability
- Microcomputer timer function: auto start, auto stop and set time announcement
- Stainless for whole interior with excellent chemical resistance and durability
- Latch integrated door handle that makes door opening easier by one hand
* Above features follow the previous models MIR-162/262 and there is no change.
Caution
* Parts replacement and option unit installation must be done by trained serviceman.

Condition of alarming:
When chamber temperature (TEMP.PV) is deviated more than
±2.5℃ from current set value (TEMP.SV).
Action:
Blinking all digits in temperature display area, alarm lamp lighting
and intermittent buzzer sounds after 3 seconds. Operation
continues.
If chamber temperature is in above range again, alarm is
cancelled.
5.
Alarm/Safety Function
Auto Set Temperature
Alarm:
When chamber temperature is deviated more than ±2.5℃ from
current set value, all digits of displayed value blink and
intermittent buzzer sounds after 3 seconds.
If chamber temperature is in above range again during alarm
sounding, alarm is stopped.
Auto Return:
There is no key operation for about 45 seconds during setting mode,
return to chamber temperature display.
Key Lock:
When key lock switch is ON, it cannot accept any key operation
except CALL key.
Memory Backup
during Power Failure:
If there is power failure during operation, restart operation after
power supply recovery and delay timer works.
If the unit is in timer mode, it continues timer mode after power supply
recovery.

Error Code
E01:
When temperature sensor is judged as open or short circuit, E01
display blinks, ALARM lamp lights, intermittent buzzer sounds, relay
and heater are turned OFF.
E02:
When heater is ON condition, but heater ON cannot be detected, it is
judged as triac open circuit. E02 display blinks, ALARM lamp lights,
intermittent buzzer sounds, relay and heater are turned OFF.
E03:
When heater is OFF condition, but heater ON is detected, it is judged
as triac short circuit. E02 display blinks, ALARM lamp lights,
intermittent buzzer sounds, relay and heater are turned OFF.
E04:
When power relay is short circuit, E04 display blinks, ALARM lamp
lights, intermittent buzzer sounds, relay and heater are turned OFF.
-10-
E05:
When power relay ON is not detected or temperature around PCB is
65℃ or more by AT sensor on PCB, it is judged as abnormal. E05
display blinks, ALARM lamp lights, intermittent buzzer sounds, relay
and heater are turned OFF.

Function Mode
<How to enter
Function Mode>
1. Keep pressing UP key for about 5 seconds or more at chamber
temperature display condition when the unit is not working to
enter function mode. Use UP key and SHIFT key to input
function code into temperature display area and press CALL
key.
2. Keep pressing UP key for about 5 seconds or more at chamber
temperature display or remain time display during operation to
enter function mode. It cannot be entered at set temperature
display and set time display.
3. Turn ON the TEST switch (DIP SW) on PCB to enter function
mode immediately (“384” input in F06 is not necessary). Once
entering function mode by this method, function mode cannot
be cancelled by switching OFF the TEST switch (unless
inputting “000” in F06 again or turning OFF the power supply).
Function Mode List
F00: Cancel function mode
F06: Input service code (code: 384)……..necessary for service
(necessary for following function mode)
F07: Zero adjustment volume value
F08: Filter pass function for temperature display setting
F09: Non-volatile memory (EEPROM) initialization
(but zero adjustment data in F11 is not initialized)
F10: Program version display
F11: Zero adjustment setting
F12: Thermistor sensor detecting temperature display
F21: Communication equipment address (ID) setting
F22: Communication parameter setting
Each Function Mode Explanation
F06:
<Purpose>
<Operation>
Input service code to use the function from F07.
Service code: 384
Input “F06” and press CALL key to show “000”. Use UP key and
SHIFT key to input service code “384” and press CALL key, then
return to current display and function from F07 can be used.
If trying to enter the function from F07 without inputting service
code, for example, pressing CALL key with “F07” display,
continuous buzzer sounds for 1 second and “F07” display does
-11-
<Note>
not change. In this case, F07 can be used after inputting service
code in F06.
Above service code input can be valid unless inputting “000” in
F06 again or switch OFF power supply.
F07:
<Purpose>
<Operation>
<Contents>
<Example>
Display zero adjustment volume (VR1 on main PCB) set value.
Input “F07” and press CALL key to show zero adjustment volume
set value.
Zero adjustment data by volume is exchanged to the value in
range of ±6.5℃ and add to temperature sensor data. Its zero
adjustment data can be shown and checked (but it takes some
time for response). Press CALL key to return to chamber
temperature display mode (or return by PV auto return). It cannot
be written in non-volatile memory. A decimal point is not shown.
-2.5℃: - 2 5
4th digit is blank, 3rd digit is blank (+) or -,
2nd and 1st digit is numerical value (no decimal point).
F08:
<Purpose>
<Operation>
Control temperature with primary delay filtering by software is
used for temperature display to prevent flickering. Display the
temperature with reducing this delay (temperature display
response become quicker).
Input “F08” and press CALL key to show “000” (initial value). Use
UP key to input “001” and press CALL key to return to
temperature display with reducing filter. It is valid until input “000”
in F08 again or switch OFF power supply.
F09:
<Purpose>
<Operation>
Initialize non-volatile memory. But, zero adjustment data in F11 is
not initialized.
This function is used when non-volatile memory data is broken by
unexpected cause (noise, etc.) and cannot be recovered.
Therefore, it should not be used normally.
Input “F09” and press CALL key to show “000”. Input “1” to 1st digit
and press CALL key to initialize all data in non-volatile memory.

+19.9 to -19.9℃.
Input “F11” and press CALL key to show current set value.
Use UP key and SHIFT key to input value and press CALL key.
Zero adjustment data set in F11 is stored in non-volatile memory
and it is not initialized. If it is needed to change to 0.0℃, it must be
changed in F11.
