6.5 IQ6500 Second Channel Setup
For second channel operation, configure the unit using the spec codes. SPECs 02, 03, and 04 are used for second channel
setup. Use the IQ6500 display resolution chart (Section 6.2.2) in conjunction with the IQ6500 spec tables in Section 6.4
to determine settings for SPEC02 (Grads) and SPEC03 (Decimal).
For example, you would perform the following steps if you were attempting to connect a 2000 lb. capacity external scale
to your IQ6500.
1. Determine the current display resolution using the IQ6500 spec table in Section 6.3 and viewing SPEC04, bits 1
and 0. For our example, we’ll say SPEC04 is set at xx00, or 1/10,000.
2. Find the 2000 lb. capacity scale in the chart above and move across to the next column (1/10,000). The display
resolution is 0.2. This value is used to set both SPEC02 and SPEC03.
3. Find SPEC02 in the IQ6500 spec table (Section 6.3). For a display resolution of 0.2, use 2 as the grads value.
Move across the column and see that SPEC02 should be set to 0000.
4. Find SPEC03 in the IQ6500 spec table. For a display resolution of 0.2, use 0.0 (one decimal position) as the
decimal value. The spec table shows that SPEC03 should be set to 0001.
To enable the second channel option, SPEC04 bit 3 must be set to 1.
Note: To calibrate, SCALE must be set to scale 2. See Section 7.0 for calibration procedures.
