PLC = Integration in Power Line Cycles. When using integration times of 100 PLC, 10 PLC, or 1 PLC; multiply Number of Counts in the table by 0.1 for 5 1/2 digit readings, 0.01 for 4 1/2 digit readings and 0.001 for 3 1/2 digit readings. Tcal = Temperature ambient during calibration (should 18-28°C).
TEMPERATURE COEFFICIENT: +/-(% of Reading + Number of Counts)/°C 6 1/2 digits displayed, Auto zero OFF are given for a stable environment (+/-1°C) and over a ten minute period. Multiply number of counts by 0.1 for 5 1/2 digits, 0.01 for 4 1/2 digits and 0.001 for 3 1/2 digits.
