Anderson Manufacturing AV-9000 manual Calibration, 11-1, Specifications listed below

Section 11 - Calibration

Calibration describes all possible field calibration procedures for the recorder as well as methods of invoking default program and calibration values. The procedures described include the input and range calibration as well as chart calibration.

From the Normal Display, press the until CALIBRATION appears in the lower display line. If PASSWORD appears in the lower display line, the correct "password" will need to be entered before access to Calibration is allowed. If CALIBRATION is not displayed, then Calibration has been disabled. Refer to Section 9, Enables and Passwords, for instructions to enable Calibration.

Press the to display CALIBRATION in the upper display and SOLENOID ADJUSTMENT in the lower

display line. Press the to advance the lower display to other calibrations available.

The table below (Table 11-1) lists the calibration routines. All instruments are calibrated prior to shipment from the factory.

CAUTION: Do not attempt any calibration without the proper test equipment that meets or exceeds the

specifications listed below.

RTD Inputs:	Decade box with 0.01% resolution or equivalent OR 100 ohm ± 0.01% AND 277
	ohm ± 0.01%.
CURRENT Inputs:	0.00 mA to 20.00 mA Source ± 0.01 mA DC
* TC or 0/25 mV Inputs:	0.00 mV to 25.00 mV Source ± 0.01 mV DC
*TC or 0/100 mV Inputs:	0.00 mV to 100.00 mV Source ± 0.01 mV DC
0 to 1 VOLT Inputs:	0.00	V to 1.00 V ± 0.01 V DC
0 to 10 VOLT Inputs:	0.00	V to 10.00 V ± 0.01 V DC
:

*For TC only - one (1) mercury thermometer ± .25 deg. C or equivalent and a Type X thermocouple; X = type of TC input being calibrated.

TABLE 11-1 CALIBRATION ROUTINES

Input Calibration	Performs calibration of all input sources
Parameter Defaults	Invokes the default values for all program parameters
Chart Calibration	Performs calibration of the pen to the chart. It is recommended that chart
	calibration be performed whenever the chart size is changed.
Milliamp Outputs	Performs calibration of current outputs
Solenoid Adjustment	Allows calibration of the current through the solenoid driver and is adjusted at the
	factory to maximize life of the solenoid actuators. This procedure would not
	normally need to be performed in the field.
Calibration Defaults	Invokes the calibration default values.
