[. . . ] #61-494 #61-495 1 490 Series Industrial Grade Multimeter M/M/A 3 2 4 True RMS Data Logging M/M/A 5 1. Input Connectors True RMS Data Logging WARNING!DO NOT UNDER ANY CIRCUMSTANCES EXCEED THESE RATINGS: - Voltage is not to exceed 1000 Volts. - Resistance, Capacitance, Logic and Continuity functions are not to be performed on circuits capable of delivering greater than 600 Volts. [. . . ] Press the Peak Hold button while in data logging mode enables the data log-out function. The first data displayed is the last data point logged in. Pressing the v w buttons scrolls up and down through the data. Pressing the v w buttons for > 2 seconds scrolls up and down through the data at a rate of 10 data points/seconds, and stops at the reading when the button is released. Pressing the M/M/A button while in this mode toggles between the maximum and minimum values logged into memory. Pressing the range button while in this mode toggles the turning points logged-in with "MAX" or "MIN" symbol depending on the comparison from the current reading and the next reading. Press the range key again to escape. Data Log Functions (continued) Data log-in A. Press the Peak Hold button for > 2 seconds while in data logging mode enables the data log-in function. The meter begins storing data points into memory according to the selected log rate. Pressing the Peak hold button while in the mode interrupts data log-in for log-rate resetting. "PAUS" is displayed on the secondary menu while the data flow is interrupted. While data is being stored into memory, "-" is shown on the secondary display. When 40K data points have been stored, the data log-in stops, the bar is full, the "-" begins blinking, and FULL is displayed on the secondary display. Log Rate Function Press the auto hold button while in data logging mode to select the log rate. Select from 0. 5", 1", 10", 30", 60", 120", 180", 240", 300", 360", 480", and 600". Press the auto hold button to escape and return to data logging mode.

Probe input guard: The meter beeps continuously and displays "ProbE" if a probe is inserted in a current input connector for other measurement functions. Buzzer: A single beep indicates correct operation; two beeps indicate a warning or error condition. Peak Hold: ±(0. 7% +20) additional error for > 20% of full scale and pulse width greater than 0. 5mS; ±(10% +20) additional error for > 50% of full scale on 2V range. 5 6 Auto power off: The meter turns itself off within 30 minutes if no controls or settings are changed. Power-up Options: Press button while turning meter on from OFF position.
