Specifications

(Unless otherwise indicated, specifications are for 1 year in ±% of
reading @ 23°C)
General
Accuracy:
Quik-Chek 4 & 20 mA ±(0.03% of Setting + 1 LSD)
Milliamp & % Ranges ±(0.05% of Reading + 1 LSD)
Read DC Volts ±(0.05% of Span + 1 LSD)
Warm Up Time: 10 seconds to specified accuracy, 2 minutes to
maximum accuracy
Temperature Effect:
Milliamp Ranges: ±0.008% of Reading/°C
Read DC Volts: ±0.012% of Span/°C
Batteries Three "9V", (1604) batteries (Alkaline supplied and
recommended)
