Volts DC (DCV DCV) Calibration Adjustment (Secondary Output) (5550A and
5560A)
The Product begins the adjustment with internal steps. Complete a Vdc Zero on the Fluke Calibration
8588A - put a 4-wire short (Fluke PN 2540973) across the HI and LO input and sense terminals.
1. Set the 8588A as follows: Volts dc, Range Auto, NPLC 50, Guard ON (external guard).
2. Push INPUT, and then ZERO FUNC. Allow the zero function to finish.
3. When the Product shows a connect prompt, connect the 8588A for vdc measurement to the
Product as instructed on the display with low-thermal cable.
4. When the Product shows an instruction to set the Product in Operate, push OPERATE.
5. Measure with the meter and input the value on the touch screen in the Enter Measured Value field.
Note that the Product only accepts values in base units. Example: a measurement output shows as
100.00000 mV, but the Product expects the value to be input in V.
6. Continue to follow the instructions on screen OPERATE/Measure/Input Value until all steps in the
function are complete.
7. When a section is complete, the Product highlights the following section.
Amps AC Calibration Adjustment
The Product prompts for the connection of VI Aux terminals to a current DMM. This procedure is a
simplified method that does not produce the greatest TUR (Test Uncertainty Ratio). Advanced
calibration laboratories can use modified methods to improve TUR. Alternatively, one can use the
meter with shunts as in the calibration verification section. To proceed, put the meter into amps ac
mode. To use the high-accuracy mode (shunts with a meter), you must determine and connect the
shunt model for each step. Failure to connect appropriate shunt may result in shunt damage.
1. Set the 8588A as follows: Amps ac, Range Auto, NPLC 50, Guard ON (external guard).
2. When the Product shows a connect prompt, connect the 8588A for Iac measurement with heavy-
gauge low-thermal cable. Tap Continue after the connection is made.
3. When the Product shows an instruction to set the Product in Operate, push OPERATE.
4. Measure with the meter and input the value on the touch screen in the Enter Measured Value field.
Note that the Product only accepts values in base units. Example: a measurement output is shown
as 12.100 mA, but the Product expects the value to be input in A.
5. Continue to follow the on-screen instructions for OPERATE/Measure/Input Value and/or switching
to the high-current output via OUTPUT LO/SENSE 30 terminals until all steps in the function are
complete.
6. When a section is complete, the Product highlights the following section.
Volts AC (ACV ACV) Calibration Adjustment (Secondary Output) (5550A and
5560A)
Use the Fluke Calibration 5790B AC Measurement Standard to accomplish the volts ac calibration
adjustment.
1. Set the 5790B for Input 2, Auto range, High resolution ON, EXT GUARD.
2. When the Product shows a connect prompt, tap Continue.
3. Push OPERATE to set the Product to operate.
