Instrument settings

The following parameters can be changed on an instrument:
Name
Password
1
Operating signal LED
1
Horn operating signal
Switch-off mode
2
Shift length (TWA)
Short-term exposure level (STEL)
1) At least one of the two operating signals must be switched on.
2) Corresponds to averaging time and is used to calculate the TWA exposure value.
3) Interpretation only if the sensor is designed for this.
4) Corresponds to averaging time and is used to calculate the STEL exposure value.

3.3 Check of parameters
To ensure that the values were correctly transferred to the gas
detection instrument:
1. In CC Vision select the button Data from X-am 1/2/5x00.
2. Check parameters.
4 Operation
4.1

Preparations for operation

Before using the instrument for the first time, insert the enclosed

batteries or a charged NiMH power pack T4 (type HBT 0000,
order no. 83 18 704) / T4 HC (type HBT 0100, order no. 83 22 244),
see chapter 4.9.1 on page 25.
The instrument is now ready for operation.

Switching on the instrument

1. Press and hold the [OK] key for approx. 3 seconds until the
countdown » 3 . 2 . 1 « shown in the display has elapsed.
All the display segments, including the visual, audible and

vibration alarms, are activated for a short time.
The software version is displayed.

The instrument performs a self-test.

The sensor that is up next for calibration is displayed with

the remaining days
CH4 %LEL CAL 20.
The time until the bump test interval elapses is displayed in

days, e.g. bt 123.
All alarm thresholds A1 and A2 as well as

1
(STEL) for all toxic gases (e. g. H
