CONNECTING GL240 TO GL840 VIA USB
Step 1: Download and install both the USB driver and the APS software from our web site.

Step 2: Onced you have downloaded and installed both items, proceed to opening the GL240/840 APS software. You will get this screen onced open and next you will click on the connect button on the top right hand corner of the APS software (highlighted in red).
Step 3: You will now get a pop up window and will see many options. You will most likely be connecting up one GL on your computer and select connect on the top Column (highlighted in blue). Select which GL you are connecting to the computer using the drop down menu (highlighted in red). Next make sure the USB ID numbers matches on your GL and APS Software. You can check this on your GL by hitting the MENU button on the actual device and scroll through the menu to the I/F tab. Here you will see the USB settings and your USB ID. Double check the USB ID with what’s on your APS (highlighted in yellow). Now that everything correlates with one another, choose the connect button located to the right of your USB ID number which was highlighted in yellow and then click the close buttons for your setting to take place and load the GL to the computer.
MAXIMUM VOLTAGE MEASUREMENT
GL240/GL840 Max Voltage is 110V; Can I measure higher voltages?
Yes, but only if you use a Voltage Attenuator. The Voltage going into the GL must remain less than or equal to 110V. The withstand voltage of the GL240/840 is 350V P-P for up to 1 minute. This means that the instrument can withstand up to 350V for up to 1 minute, but any time thereafter may cause the terminals to burn out. We recommend keeping the voltage levels within the recommended specification.
TURN ON PULSE / LOGIC
Step 1: From the main screen on your unit, hit the “MENU” button to proceed the menu screen.
Step 2: Once the “MENU” screen has come up, scroll down using the down arrow key.
Step 3: Scroll down once until you reach the “Display Logic/Pulse Data” and hit the “ENTER” Button.
Step 4: Once at the “making analog and pulse/logic settings” Menu, on the Logic/Pulse option, choose which one you would like to use. Either Pulse or Logic.
Step 5: Now choose which Input you would like to use, you have 3 different options to choose from.
Step 6: You can also use the Engineering scale to make sure the signal you have coming in is correct. When you are setting the high and lows for your pulse/ logic signal, the first column which says measured value will be your voltage range of the sensor that you are using. The second column, which is EU value will be the range at which your sensor can read (ex: 0 – 60 PSI).
Step 7: Once all of your values are set, you can hit QUIT on the GL to return to the main screen.
ADJUST TEMPERATURE TO ZERO
Step 1: From your GLXXX main screen hit the MENU button.
Step 2: When on the MENU screen, Scroll down to the channels you will be using to measure.

Step 4: Turn the EU Setting to on (highlighted in red). To set your adjustment you will use the adjust values. The Measured (highlighted in blue) will be what your Temperature is reading and your EU value (highlighted in yellow) will be what you want it adjusted to. SO if your temperature is off by 30 and you want to measure 0, then set the measured value to 30 and the EU value to 0. Once you values are set, click ok on the drop down menu to save settings.
Step 5: You can proceed with changing other channels to what you need or you can hit the QUIT button to exit back to the main screen.

Step 6: After your file is selected, you will see what you chose pop up in the batch menu. From this point, you can either add more files to the batch or you can select start batch conversion (highlighted in red) which will convert the file you have selected.
ADJUSTING SCALLING FOR SENSOR - TRANSDUCER MEASUREMENT ON GL840
STEP 1: Open up your GL unit and connect your GL to it by matching up the USB ID on the unit and the software.
STEP 2: Once connected, here click on the MENU button highlighted in red.
STEP 3: Once the settings window pops open, on the first tab which is the AMP Settings, turn on the scaling on the channels you would like to change (highlighted in red). Once turned on, the channels that have the scaling on will turn blue as shown above.
STEP 4: When a channel is turned on, a scaling window will pop open and from this window, you will set the scaling to your needs. If your GL is measuring off and you need to add .1 V to a channel then under the measured value on the left (highlighted in red) you would set the value of what you are measuring, such as from 0V to 2V. On the EU value (highlighted in blue), this is where you will set the offset or what you are scaling too. Because you want to add .1V, you will put the upper .1above 2 and same goes for the lower value as shown in the above picture. Select ok to save an exit out.
STEP 5: Once you have finished with your settings, you can click APPLY and then OK at the bottom left hand corner of the Settings window. You are now ready to start your adjusted measurements.
