SETTING PROCEDURE: Enter the SET UP mode by turning ‘ON’ the power while pressing and holding the [CH UP] ( ENT) key until the SET UP display appears.
7.3 Setting A/D Integration Time (Pen model) The purpose of the following setting is to specify which A/D integration time will be used. Depending on the power supply, the integration time will affect the ability of noise rejection and therefore the recording. If the power supply of the recorder and of the measuring object are the same, the effect of noise will be automatically minimized and the (initial) value of AUTO is the recommended one.
7.4 Setting Upscale/Downscale TC Burnout 7.4 Setting Upscale/Downscale TC Burnout The purpose of the following setting is to specify where the pens will move in the case of a TC-burnout. You can choose from moving to the right (UP) or to the left (DOWN). This is common for every channel. You can select ON or OFF for each channel. The initial value is ‘UP’, and ‘OFF’ for every channel.
7.5 Configuring the Input Filter (Pen Model) Noise in the measured signal can be suppressed in the final measurement by using an input filter. The purpose of this setting is to select for each channel whether or not to use a filter, and if so, to select a time constant of damping. A filter works as follows: Input Response curve (Filter OFF) Meas. values 63.2% Response curve (Filter ON) 2, 5 or 10 sec.
