### Description

The AC volts true RMS input module is a universal module designed to function with the Lynx, Leopard, and Tiger range of indicators, meter relays, and programmable meter controllers (PMCs). Commonly used in the 0 to 200 V range, a 0 to 200/600 V range header provides the option to go to a higher v oltage.

The IA06 has a diff erential input with common mode filter ing and a v oltage divider to atten uate the high input v oltage to safe levels.

Zero input voltage produces a 0 output signal, meaning no z ero adjustment is necessar y.

Tiger Controllers and Leopard Meter Relays The Tiger and Leopard r ange use inter nal software functions to calibr ate the span. However, it may be necessar y to adjust the sp an potentiometer to bring the maximum input signal within the full scale r ange of the instrument.

When the input signal is be yond the full scale r ange of a Tiger controller, the display flashes [OVER]. When the input signal is be yond the full scale, the top range of a Leopard meter segment of each digit of the displa y flashes.

Figure 2 Span Potentiometer Adjustment

Turn the 15 tur n span potentiometer counter-clockwise to decrease the signal until a reading appears on the display (See Figure 2). Now calibrate the instr ument using the softw are calibration method f or y our instr ument.

Figure 3 Span Pot

Lynx Indicators

The span potentiometer is the only means of calibr ating Lynx indicators. When the input signal is beyond the full scale range of a Lynx indicator, a 1 is displayed in the most significant digit

(MSD) with all other digits b lank. Turn the 15 tur n span potentiometer counter-clockwise to decrease the signal until a reading appears on the display (See Figure 2).

Span Potentiometer (Pot)

The 15 tur n span potentiometer is located on the r side of the input module (when vie wed from the rear of the meter). Typical adjustment is 20% of the input signal r (See Figure 3).
