Altek 830-KP manual Read Milliamp Outputs, Read DC and AC Voltage Outputs MV, V, Vhi and Vac

OPERATING INSTRUCTIONS

READ MILLIAMP OUTPUTS

mA, mA % (Percent of 4 to 20 mA), DP% (DP Flow)

Choose this function to measure from 0.00 to +24.00 milliamps.

1)Open the current loop at any convenient point along the signal path

2)Press the MILLIAMP/V push-button until mA or mA and % appear on the display

3)Press the DISPLAY/SOURCE/READ push-button until READ appears on the display

4)Press the mA/%/% DP FLOW push-button to display mA, % 4-20 or % DP Flow.

5)Connect the red READ (+) lead of the calibrator to the more positive point of the break and the black READ lead (-) to the more negative

Display the present reading, Maximum or Minimum by pressing the READ, MAX or MIN push-buttons. If the TechChek 830-KP is connected in the wrong polarity, the word POL will flash on the display. Simply reverse the leads for correct indication.

OPERATING INSTRUCTIONS

READ DC and AC VOLTAGE OUTPUTS

mV, V, Vhi and Vac

Choose this function to measure from 0.00 to 110.00 millivolts (mV),

0.00to 10.25 DC Volts (V). Use the high voltage connection to read from 0.0 to 200.0 VDC (Vhi). See the next page for Volts AC.

1)Press the MILLIAMP/V push-button until mV, V, Vhi or VAC appear on the display

3)Press the DISPLAY/SOURCE/READ push-button until READ appears on the display

4)Press the TYPE/ENG UNITS push-button to select mV, V, Vhi or VAC on the display

5)Connect the red READ (+) lead and the black READ (-) lead of the calibrator across the voltage to be measured.

Signals above or below those available for the currently selected range will be indicated by OVER and UNDER on the display.
