DESCRIPTION
MODEL
VIEW DATA
The GasCheck instrument has the ability to data log 10 readings within its internal
memory. To tore a reading, press the ENTER key while on the main RUNNING SCREEN.
When readings are stored in memory, a symbol will appear on the main viewing screen.
When the memory is full, the Data symbol will flash. The stored data can be viewed by
scrolling through the logged readings using the UP and DOWN keys.
To delete the stored data:
1. Press and hold the ENTER key.
2. The TRASH CAN symbol will flash.
3. Continue to hold the ENTER key until the data is deleted.
4. Press the ESC key to exit to the MAIN MENU.

UNITS
GasCheck instruments have the capability of displaying detected readings in a
variation of units: ppm, cc/s, mgm3, and g/yr.
Use the UP and DOWN keys to select the desired unit, and then press the ESC key to
exit to the MAIN MENU.
NOTE: the Custom Calibration routine automatically selects the type a calibration
depending on his setting. See 5.1 CALIBRATION.
• CC/SEC = cubic centimeters per second offers a volumetric leak rate that directly
measures the volume of a gas escaping from a given point. It is also known as ml/
sec (milliliters per second). The GasCheck can typically detect helium leaks down to
0.0005 of a cubic centimeter per second.
• PPM = Parts per million. This unit indicates a concentration but can’t be used to
quantify a volume of gas leakage.
• MG/M3 = Milligrams per meter cubed. Like ppm, this unit is also a concentration, so
it can’t be used to quantify a volume of gas leakage.
• G/YR = Grams per year offers an alternative volumetric leak rate that directly
measures the volume of a gas escaping from a given point.

DISPLAY
The GasCheck has the capability of displaying a cc/sec and g/yr reading in either
decimal or exponent form. (Readings in ppm and mg/m3 can only be displayed in
decimal form.)
To change the display:
1. Use the UP and DOWN keys to select the desired unit.
2. Press the ENTER key to display the next screen.
3. Use the UP and DOWN keys to select the desired display and then press the ESC key
twice to exit to the MAIN MENU.

UPGRADE
The GasCheck instrument can be upgraded using a simple upgrade code. This facility
allows the GasCheck to be upgraded instantly by the user in the field. See Table 7:
GasCheck Feature Comparison to compare the various features within each model.
To upgrade a GasCheck, simply purchase an upgrade code from Portable Leak
Detectors, enter the 12-digit number on the upgrade screen using the UP, DOWN,
ENTER, and ESC keys. Once all 12 digits are entered correctly the instrument will
automatically switch off.
When the instrument is switched on, the new instrument model number will be
displayed.
