SAFETY INFORMATION

Incorrect operation or unsuitable using environment may attenuate the instrument’s performance. Therefore, please first

read the below safety information carefully before using and then operate this device.

Please don't use the defective device. Before using, please check if there is crack or spare part missing. If yes,

please contact the seller immediately.

It's suggested that the user carry out the "Bump Test" by following Clause 5.3 of this manual before using the

device. If the device reading is beyond the specified range, please calibrate the device by following Clause 5.7 and

5.8 of this manual.

Periodic Bump test will test the response feature of the sensor. Please make sure that the visual, audible and

vibrative alarm signals are ok.

Only accessories which are specified for IMR EX660 or permitted by the seller are allowed to be used.

Only the charger which is specified for IMR EX660 is allowed to be used. It's forbidden to charge the device in

the dangerous environment.

Please don't expose the device to the exceeding-range gas environment for long time. Otherwise, it will badly

influence the performance and even damage the device.

If exposed to the environment consisting of leaded compound, sulfocompound, organic phosphorus compound or

silicon, the gas sensor will be poisoned. Please don't use the device in the above environment.

Please don't expose the device to the environment which consists of H2S, hydrocarbons gas or high corrosive gas

for long time. Otherwise, it will restrain the response of the gas sensor and reduce the sensitivity. If the device has

to be used in the above environment, please follow Clause 5.3 to carry out the Bump Test before using it.

Please don't expose the device to the environment which has electric shock, strong magnetic field or serious

continuous mechanic shocking.

There is a lithium battery inside the device. Please don't place the useless battery together with the rubbish. The

useless battery should be discarded by qualified withdrawers.

It's forbidden to disassembly, adjust or repair the device without permission.

Please avoid the device falling from high place or serious shocking.

Any other operation beyond this manual, please contact the seller.

5. Operation Instructions

5.1 Power on

When machine is power off, hold for more than 3s and the device will be power on. The screen shows as

below.

IMR Environmental Equipment, Inc.

IMR EX660

After power on, the detector will proceed self-test and display is as below drawing.

The device will make self-test on the buzzer, alarm lights and vibrator automatically. After self-test, the device enters

into normal detection status and the screen displays as below.

Note:

If self-test fails, related information will be displayed. For details, please refer to Clause 10 Troubleshooting of

this manual.

If self-test succeeds, the device enters into warm-up period of 3-30s, which depends on the sensor type.

5.2 Power off

In normal detection status, hold for 3 seconds and the screen will show “Shutting down…”. Meanwhile, the

buzzer will give out intermittent beep twice. Then machine is power off.

5.3 Bump test

Every day before using the device, the user is suggested carry out Bump test, so as to check if the device is working

normally.

Test method:

When the device is power on, put it into high level gas environment, which is higher than the preset high alarm point of

the device. If the entire device’s function is ok, then device can be used in the working area.

Note:

If any reading on the screen is beyond the prescribed display error range, please follow Clause 5.7 and 5.8 of this

manual to re-calibrate it.

Note:

Do not block sensors in detecting process.

To prolong life span, external filters are suggested in detecting process.

Long time storage, serve physical shock and excessively high concentration may cause zero drift of the gas

sensors. If finding the reading in clean air is not zero, please make zero calibration by following Clause 6.7 and

6.8 of this manual.
