Safety Instructions | CS LD 1.0 | 33 | en

3. Safety Instructions

All safety instructions are to be

read thoroughly before using the

CS LD 1.0 and they must be ob-

served.

• Avoid operating the CS LD 1.0

in direct sunlight and areas of

excessive dust, high humidity,

high temperature, large tem-

perature fluctuations or mag-

netic fields, which may cause

malfunctions and/or inaccurate

readings.

• Do not attempt to repair the

CS LD 1.0

• The CS LD 1.0 display may only

be cleaned with a soft cloth

and neutral cleaning agents.

• Do not use any abrasive

cleaning agent or rough

cleaning cloths.

• The CS LD 1.0 operates on a

lithium-ion type battery. For

long battery life and safe opera-

tion, observe all warnings.

• For prolonged and safe opera-

tion, always ensure to charge

the CS LD 1.0 battery between

ambient temperatures of 0 °C

and 45 °C.

• Disconnect the charger from

the power source when not in

use or charge is complete.

• Do not try to access the batte-

ry, contact Bosch customer ser-

vice for battery replacement.

➢Do not disassemble or

attempt to repair the

battery or protective

circuit.

➢Do not put the

CS LD 1.0 near a fire or

hot surfaces or in a hot

vehicle or under direct

sunlight as there is

chance of battery over-

heating and explosion.

➢Do not expose the

battery to temperatures

above 60 °C (140 °F).

• Do not subject the CS LD 1.0

to impact. Do not deform, pier-

ce, or damage the battery.

Do not touch a battery that

appears to be leaking or da-

maged. If battery fluid gets

in your eyes, flush with fresh

water, do not rub eyes, and

seek medical attention.

Do not keep the CS LD 1.0 unused

for extended periods to avoid da-

mage to the battery. The correct

storage environment is critical to

battery life.

• The battery should have a 40 %

to 50 % charge during prolon-

ged storage (a month or more).

• The battery should be stored in

an environment with less than

75 % RH.

iiBattery life will be reduced sig-

nificantly if the battery is stored

with a full charge and/or at high

temperatures.

!Always ensure to use a charger

certified according to local

guidelines with an output rating

of 5V DC 1A for charging the

CS LD 1.0 (battery).

Risk of fire

➢Do not use the

CS LD 1.0 in the

vicinity of spilled

or open containers

of gasoline or other

flammable subs-

tances.

➢The CS LD 1.0

is designed to

operate in normal

or non-hazardous

environments. Do

not use this equip-

ment in hazardous/

explosive environ-

ments.

4. Product description

4.1 Application

The CS LD 1.0 is used for detecting

leaks of refrigerant during service

/ repair of A/C or refrigeration sys-

tems.

5. Commissioning

1. Remove the transport pa-

ckaging.

2. Check if all items have been

delivered as per section 4.2.

3. Check the CS LD 1.0 for dama-

ges. If there are damages, con-

tact Bosch customer service.

4. Read this operators manual.

5. Charge the CS LD 1.0 (refer

to Sec. 7.4.2) using the provi-

ded charging block and cable.

An alternate charger certified

according to local guidelines

with output rating of 5V DC

1A minimum may be used,

however charging time may be

increased.

6. Once connected to the charger,

the CS LD 1.0 LCD will illumi-

nate to indicate that the battery

is charging and shows % charge

status. If the display does not

illuminate, check the power

source or verify the charger

compatibility and/or connec-

tion.

iiAvoid discharging the battery

completely. Recharging a par-

tially discharged battery more

frequently is better for the life

of a lithium-ion battery.

iiOnce fully charged, as in-

dicated on the display, the

CS LD 1.0 is ready for use.

6.1.1 Adjusting sensitivity

levels

F 002 DG9 H12 | Bosch Automotive Service Solutions GmbH2021-04-08

36 | CS LD 1.0 | Operating Instructions

en |

The unit will default to the Medi-

um sensitivity level and Automatic

mode (indicated as shown in item

8, Fig. 1.1 ) once the unit comple-

tes the warm up cycle. To change

sensitivity levels, press the Sensi-

tivity button (item 6, Fig. 1.1) once

for High sensitivity (three bars)

and again for Low sensitivity (one

bar). Pressing a third time returns

the sensitivity level to Medium.

iiThe sensitivity level can only be

changed in Automatic mode.

For more information on, and inst-

ructions for changing modes, refer

to Section 6.1.2 Automatic and

Manual Reset Modes.

6.1.2 Automatic and Manual

Reset Modes

To allow the user to find the leak

source easily, the detector can

re-calibrate itself either automati-

cally (default) or be manually re-

calibrated to the ambient level of

refigerant and reset (or zero) the

alarm after there is a detection.

In Automatic mode the Aicon will

appear in the lower left of the

screen as shown in Fig. 2. In this

mode, after an initial alarm, if the

refrigerant concentration detected

is not increased, the detector will

automatically reset the alarm af-

ter approximately 3 seconds. The

CS LD 1.0 will now only alarm to

higher concentrations. To automati-

cally return to maximum sensitivity

(for the given level set), move the

probe tip into fresh air for a few

seconds.

Fig. 2: Automatic mode icon

To use the detector in Manual

mode: Press and hold the Sensiti-

vity button and release when the

A(AUTO) icon is replaced with M

(MANUAL) on the display. In Manu-

al mode, the screen will display the

Micon (Fig. 3) rather than the A. In

this mode, the detector will conti-

nue to alarm if refrigerant is detec-

ted until the user presses the Sen-

sitivity button to manually reset the

alarm or the probe is moved away

from the source of refrigerant.

Fig. 3: Manual mode icon

Both modes allow the user to get

closer to the leak source without

the detector continually alarming

by essentially resetting the “base-

line” detection level.To return to

Automatic mode, press and

hold the Sensitivity button and

release when the Aicon is dis-

played.

To reset the alarm in Manual mode,

briefly press the Sensitivity button.

The display will show the Micon

with the reset arrow as shown in

Fig. 4.
