DESCRIPTION OF FUNCTION KEYS

4.2.1. Key HOLD/REL

Pressing key HOLD/REL freezes the value of the measured quantity on the display. After
pressing this key, the message
again to quit the function. To save the value on the display, see § 4.3.4. Key HOLD/REL
also allows quitting the programming menu, going back to the instrument
measuring screen and restores the display
OFF mode. Press longer the HOLD/REL key in order to activate/deactivate the relative
measurement on the selected function (see § 4.3.5).

4.2.2. Key RANGE

Press key RANGE to activate manual mode and disable the Autorange function. The
symbol Manual Range
"
change measuring range: the relevant decimal point will change its position and the full
scale value in the bargraph will change too. Key RANGE is not active in positions
Type K and 60A
most appropriate ratio for carrying out measurement. If a reading is higher than the
maximum measurable value, the indication
key RANGE for more than 1 second to exit the manual mode and restore the Autorange
mode.

4.2.3. Key MODE/VFD

Pressing key MODE allows selecting a double function on the rotary switch. In particular, it
is active in position
test, capacity test and measurement of resistance, in position TypeK for the selection of
temperature measurement in °C,°F or K, Hz% for the selection of frequency measurement
and duty cycle, VAC+DC
(see § 4.3.3), V
frequency and duty cycle of AC voltage, LoZAC+DC for the selection of AC voltage with
low impedance measurement (see § 4.3.8) "V
1000A
for the selection of AC and DC current measurement for the selection of AC, DC and
A (AC+DC) current measurement. In position
MODE/VFD allows selecting the type of clamp, Standard (
positions VAC+DC
allows to activate/deactivate the VFD (Variable Frequency Driver) measurement mode
(see § 4.3.9) in order to evaluate the AC voltage and current downstream variable
frequency drivers (inverters)
