10.2 Output Calibration

Introduction

The 9782 is available with one or more optional analog outputs. The output signals can be adjusted to trim the high and low output current or voltage values over a range of ±0.4% of span to compensate for component tolerance variations.

Required equipment

Output calibration involves connecting a meter to the Analyzer/Controller’s output terminals. The meter required for output calibration depends on the type of outputs.

∙current outputs: current meter capable of resolving 0.01 mA over the range 0 to 20 mA dc

∙voltage outputs: a 250 ohm ±0.05% shunt and a volt meter (capable of measuring 1 to 5 Vdc within 1 mV)

A screwdriver to fit the terminal block screws is also required.

Procedure

To calibrate outputs, follow the procedure described in Table 10-1. The output terminals are inside the case as shown in Figure 6-1.

WARNING

While the unit is powered, a potentially lethal shock hazard exists inside the case. Do not open the case while the unit is powered. Do not access the output terminal as described below while the unit is powered.

WARNING

A disconnect switch must be installed to break all current carrying conductors. Turn off power before working on conductors. Failure to observe this precaution may result in serious personal injury.
