Diode Test and Continuity Test

Diode test indication: display voltage drop: 0.2 mA

nominal test current at 0.6V: 2.4V full scale, accuracy

±(2% + 1 count)

Continuity test indication: continuous audible tone for test resistance <100Ω

Open circuit voltage: <3.9V

Short circuit current: 1.2 mA typical

Overload protection: 1000V rms

DC Current Output

Source mode:

Span: 0 mA or 4 mA to 20 mA, with overrange to 24 mA

Accuracy: 0.05% of span

Compliance voltage: 12V with battery voltage >8.5V

Simulate Mode:

Span: 0 mA or 4 mA to 20 mA, with overrange to 24 mA

Accuracy: 0.05% of span

Loop voltage: 24V nominal, 30V maximum, 15V minimum

Compliance voltage: 21V for 24V supply

Burden voltage: <3V

General Specifications

Maximum voltage applied between any jack and earth ground: 1000V

Storage temperature: -40°C to 60°C

Operating temperature: -20°C to 55°C

Operating altitude: 2000 meters maximum

Temperature coefficient: 0.05 x specified accuracy per °C for temperatures <18°C or >28°C

Accuracy adders for use in RF Fields: In an RF field of 3V/m, change the accuracy specifications as follows:

For DC Millivolts Measrement, add 0.03% of range For AC Volts Measurement, add 0.37% of range For DC Current Measurement, 30.000 mA range, add

0.14% or range

For DC Current Output, add 0.02% of span

Accuracy for all meter functions is not specified in RF fields > 3V/m.

Relative humidity: 95% up to 30°C, 75% up to 40°C, 45% up to 50°C, and 35% up to 55°C
