MX/MN (Maximum and Minimum reading mode)
The MX/MN mode permits the user to record and recall the highest and lowest readings. The MX/MN feature is available for ACA, ACV, DCV, TEMP, and µA functions only. The following steps outline the MX/MN feature:
1.Take an ACA, ACV, DCV, TEMP, or µA measurement as described earlier.
2.Press and hold the MX/MN key for 2 seconds.
3.The Elapsed Timer (top display) and the MX/MN & ® indicators will appear on the LCD.
4.The Elapsed Timer shows the duration of the measurement session in Minutes and Seconds (the Elapsed Timer switches to Hours and Minutes after 60 minutes). The maximum recording time is 100 hours.
5.The ® indicator informs the user that the measurement range is being held. Note that the AUTO POWER OFF feature is disabled in the MX/MN mode.
