[1] Input impedance: Refer to Table A on page 8.
[2] The accuracy could be 0.05% + 10 for U1251A and 0.05% + 5 for U1252A/3A. Always use the NULL function to zero out the thermal effect before measuring the signal.
[3] The accuracy of 500 W and 5 kW is specifi ed after NULL function, which is used to subtract the test lead resistance and the thermal effect.
[4] For the range of 50 MW and 500 MW, the R.H. is specifi ed for <60%.
[5] The accuracy is specifi ed for <50 nS and after NULL function with open test lead.
[6] Always use the NULL function to zero out thermal effect with open test lead before measuring the signal. If the NULL function is not used, an additional 20 counts needs to be added to the
[7] Current can be measured up to 10 A continuously. An additional 0.5% needs to be added to the specifi ed accuracy if the signal measured is in the range of 10 A~20 A for 30 seconds
[8] Maximum open voltage: <+ 4.2V.

DC current accuracy. Thermal effect could occur due to the following:
• Wrong operation to measure the high voltage of 50 V ~ 1000 V for resistance, diode, and mV measurements.
• After battery-charging has completed.
• After measuring a current greater than 440 mA, it is suggested that the meter be left to cool down for twice the measuring time used.
