4. Use or key to move across to the TRIG MODE command on the command level.
“1: TRIG MOD” will be displayed.
5. Press to move down a level to select a trigger source.
6. Using or to select between IMM, MAN or BUS trigger source.
7. Press (ENTER) to confirm the selection. The message “SAVED” will be displayed to show
that the change is now in effect. The multimeter automatically exits the parameter level and moves
up a level to the command level.
4.2.2 Reading Hold
Reading hold function is used to hold a reading on the display indefinitely. To hold a reading, do the
following:
1. Press + to hold the reading on the display at any time. To un-hold the reading and
return to normal operation, press + again.
4.3 MAX / MIN
“MAX / MIN” function enables the multimeter to record the minimum and the maximum readings. If
“MAX / MIN” function is enabled, the 2
nd parameter indicates the latest maximum or minimum reading.
Use the following procedure to turn on the MAX / MIN operation:
1. Press to enable the MAX / MIN function
2. Use or key to switch between MAX and MIN.
3. Press key again to disable the MAX/MIN function.
4.4 Limit Operations
Limit operations set and control the values that determine the HI / IN / LO status of subsequent
measurements. Limits can be applied to all measurement functions except continuity. Unit prefixes are
applied before the limit test, for example:
Low Limit = -1.0, High Limit = 1.0
A 150 mV reading equals 0.15 V (IN).
Low Limit = -1.0, High Limit = 1.0
A 0.6 kΩ reading equals 600 Ω (HI)
You can configure the multimeter to beep or not when readings are outside of the limit range.
