Safety instructions

Read the operating instructions carefully and especially observe the safety information. If you do not follow the safety instructions and information on proper handling in this manual, we assume no liability for any resulting personal injury or damage to property. Such cases will invalidate the warranty/guarantee.
7.1 General information

The device is not a toy. Keep it out of the reach of children and pets.

If you have questions that remain unanswered by these operating instructions, contact our technical support service or other technical personnel.
Maintenance, modifications, and repairs must only be completed by a technician or an authorized repair center.

7.2 Handling

Please handle the product carefully. Jolts, impacts or a fall even from a low height can damage the product.

7.3 Operating environment

Do not place the product under any mechanical stress.
Protect the appliance from extreme temperatures, strong jolts, flammable gases, steam, and solvents.
Protect the product from high humidity and moisture.
Protect the product from direct sunlight.

7.4 Operation

Consult an expert when in doubt about the operation, safety or connection of the appliance.
If it is no longer possible to operate the product safely, take it out of operation and protect it from any accidental use. DO NOT attempt to repair the product yourself. The safe operation can no longer be guaranteed if the product:
– is visibly damaged,
– is no longer working properly,
– has been stored for extended periods in poor ambient conditions or
– has been subjected to any serious transport-related stresses.

7.5 User requirements

Radiation can be hazardous to health. Persons that perform measurements in the presence of radioactivity must understand the hazards involved, be familiar with applicable guidelines, and take necessary precautions to protect themselves and others.

7.6 Batteries

Correct polarity must be observed while inserting batteries.
The batteries should be removed from the device if it is not used for a long period of time to avoid damage through leaking. Leaking or damaged batteries might cause acid burns when in contact with skin, therefore use suitable protective gloves to handle corrupted batteries.
Batteries must be kept out of reach of children. Do not leave batteries lying around, as there is a risk, that children or pets swallow them.
All batteries should be replaced at the same time. Mixing old and new batteries in the device can lead to battery leakage and device damage.
Batteries must not be dismantled, short-circuited, or thrown into the fire. Never recharge non-rechargeable batteries. There is a risk of explosion!

13 Battery compartment

Battery

9.1 Insert batteries

Remove the battery compartment cover by releasing the locking screw. Be careful not to lose the screw.
Insert 4x AA batteries matching the polarities shown.
Replace the compartment cover.

9.2 Battery voltage check
Important:

Replace the batteries before they are completely spent.
Power shut off due to low batteries will result in data loss.

1. Press the button to display the battery voltage.
– Normal range is 4.8 to 6.0 V.
– The replace battery symbol will show if the voltage is: < 4.8 V.
2. Press to exit battery voltage check.

System settings

Configure various settings through the setup menu before using the device.

Press and then ▲/ ▼to select a setting.
Press to confirm the selection or press to exit the setup menu.
– Press ▲/ ▼to adjust values.
– Press to toggle through settings.
Press to save the setting and return to the main menu.

10.1 Settings

Setting

| Description
---|---

DATE

| Year, month, day

TIME

| Hours, minutes

ALM

| When the measured value is greater than the set value, a continuous beep will sound. Settings range: 1 – 999 μSv/h (default: 205 μSv/h).
****| If set to ON, there will be a “tick” sound when radiation is de- tested.

T

| Settings range: 8 – 120 seconds (default: 30 seconds).

10.2 Factory default settings
Remove and then replace the batteries to reset all settings to factory defaults.

Operation

11.1 Select radiation type: α, β, γ, X-ray
Important:
Gently rotate the ray selector switch to prevent damage to the sensor.
In normal conditions, the sensor can detect the selected radiation value when the sensor is pointed toward the source of radiation.

Switch position	Detected ray type
Middle	Alpha (α)
Left	Beta (β)
Switch position	Detected ray type
---	---
Right	Gamma (γ)
Left, middle, right	X-ray

11.2 Power and backlight button

Press and hold the button to switch power ON/OFF.
If the product is ON, press the button to switch the backlight ON/OFF.

Note:

The backlight has a 1-minute auto shutoff time.
Data will be saved when the power is switched off.

11.3 Select radiation dose rate unit (μSv/h, mR/h)

Press the button to switch between μSv/h and Rem/h.
If the reading is too low, the bar graph will be flat.
The Sv/h and Rem/h unit conversion is based on the following formula: 10 μSv/h = 1 mRem/h.

11.4 Save data

You can save up to 4000 measurements. Saved data includes the date, time, value, and unit.
Press to start/stop saving data.
will show when data is being recorded.

11.5 Accumulated radiation dose rate
You can measure the accumulated radiation dose over time. The initial unit is μSv. If the measured dose rate increases, the unit will automatically change to mSv or Sv.
Press the button to cycle through modes:

Infinite dose rate accumulation calculation mode, “μSv” will show.
Timing measurement mode (default 60 “060” mins), “TIME” will flash.
Stop timing measurement, and “TIME” will stop flashing.

To set the measuring time:

In timing measurement mode, press and hold to set the measuring time (001 – 999 minutes).
– Press ▲/ ▼to adjust values.
– Press to toggle through settings.
After all the values have been set, pressing will save and exit settings.

11.6 Pulse counting

Mode	Description
cps	Pulse per second
cpm	Pulse per minute. Counter will automatically switch to Sv (1 Sv = 100

Rem).
Pulse counting

| Radiation is constantly measured by the Geiger tube and then converted into a pulse rate. “TIME” flashes when counting pulses, and stops flashing when stopped counting pulses.

Press the button to cycle through modes: “cps”→ “CPM” → “ ”(counting) → “ ” (stop counting).
Press to exit pulse counting.

Disposal

14.1 Product
This symbol must appear on any electrical and electronic equipment placed on the EU market. This symbol indicates that this device should not be disposed of as unsorted municipal waste at the end of its service life.
Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose of it separately from unsorted municipal waste. Spent batteries and accumulators, which are not enclosed by the WEEE, as well as lamps that can be removed from the WEEE in a non-destructive manner, must be removed by end users from the WEEE in a non-destructive manner before it is handed over to a collection point.
Distributors of electrical and electronic equipment are legally obliged to provide free take-back of waste. Conrad provides the following return options free of charge (more details on our website):

in our Conrad offices
at the Conrad collection points
at the collection points of public waste management authorities or the collection points set up by manufacturers or distributors within the meaning of the ElektroG

End users are responsible for deleting personal data from the WEEE to be disposed of.
It should be noted that different obligations about the return or recycling of WEEE may apply in countries outside of Germany.
14.2 (Rechargeable) batteries
Remove batteries/rechargeable batteries, if any, and dispose of them separately from the product. According to the Battery Directive, end users are legally obliged to return all spent batteries/rechargeable batteries; they must not be disposed of in normal household waste.
Batteries/rechargeable batteries containing hazardous substances are labeled with this symbol to indicate that disposal of household waste is forbidden. The abbreviations for heavy metals in batteries are Cd = Cadmium, Hg = Mercury, and Pb = Lead (name on (rechargeable) batteries, e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality, our stores, or wherever (rechargeable) batteries are sold. You thus fulfill your statutory obligations and contribute to environmental protection.
Batteries/rechargeable batteries that are disposed of should be protected against short circuits and their exposed terminals should be covered completely with insulating tape before disposal. Even empty batteries/rechargeable batteries can contain residual energy that may cause them to swell, burst, catch fire or explode in the event of a short circuit.
