8-6 Maintenance and Calibration PLZ-4W
8.3.2 Preparation
Leave the PLZ-4W turned on for at least 30 minutes (warm-up) before carrying out
a performance check. This is to reduce measurement errors due to initial drift. Keep
the ambient temperature at 23
± 5 ° C.
Table8-1 Test equipment used
Connect the cables as shown in Fig. 8-5. Select the shunt resistor according to the
calibration item.
