• Apply the values that follow:

mA: -55, -25, -20, -10, -5, 0 (open circuit)

mA: 0, 5, 10, 20, 25, 55.

• Check the error is in the specified limits (See Table 5-2).

PROCEDURES: CURRENT (source) 5.6

When recalibrating measure and source functions for this range, the

measure function must be adjusted before the source function.

Do the procedure as follows:

1. Connect the applicable calibration equipment

(See Table 5-1):

• CH1 (24 mA range): (See Table 5-3).

2. Let the equipment get to a stable temperature (minimum: 5

minutes since the last power on).

3. Use the calibration menu (See Section 5.4 ) to do a two-point

calibration (0.2 mA and FS):

• CH1: 24 mA.

4. Check the calibration is correct:

• Select the applicable Current (source) function

• Apply the values that follow:

mA: 0.2, 6, 12, 18, 24

• Check the error is within limits (See Table 5-3)
