Routine maintenance, Calibration of the offsets | Escort 3016B

3 Initialisation

2/ If the source of the signal to record has a low internal impedance, you will have to use twisted cables. If the impedance is high, you will have to use screened cables.

3/ When gathering the grounding from the various elements to the measure chain, youd better check that there is no difference of potential in order to avoid any short-circuit. If there is any doubt, make a measure with a voltmeter with a low charge (1k for example) between the terminals.

3.5.Routine maintenance

The ordinary maintenance is only a cleaning of the outside of the appliance. Any other operation requires qualified personnel.

Unplug the appliance before any intervention.

Do not let water flow into the appliance, in order to avoid any electrical discharge.

Regularly clean the recorder in respect with these instructions:

-use water and soap to clean the front and rear beards

-never use any product including benzine or alcohol that would damage the screen printings

-wipe with a soft non-plushy cloth

-use an anti-static product to clean the screen.

3.6.Calibration of the offsets

You can easily calibrate the inputs of the recorder for the offsets of the voltages and of the thermocouples.

To do so:

-make the appliance work for 20 minutes (outside temperature: 20 to 25C)

-for EVERY inputs, link the red "+" terminal to the black "-" terminal

-validate every channels "ON"

- press the key

and select the line Electronic Calibration and then the

menu key Calibration Offset

When pressing the Confirm menu key, you will launch the calibration procedure that will last about 10 minutes.
