7.1. ENVIRONMENTAL PARAMETER AND LEAKAGE CURRENT: REAL TIME
MEASUREMENT
This working mode allows to execute real time measurement and recording of
Environmental Parameter and Leakage current
1. Press this key to access to "
AUX" mode.
2. Pressing this function key you will change the measuring unit of the instrument's
input. The following possibilities will be displayed circularly:
- - - (Disabled instrument's input)
mA (Leakage current)
°C (Celsius Temperature)
°F (Fahrenheit Temperature)
HR% (Relative humidity)
m/s (Air Speed)
mV (Voltage)
LUX (20) (Illuminance: Full Scale 20Lux)
LUX (2k) (Illuminance: Full Scale 2kLux)
LUX (20k) (Illuminance: Full Scale 20kLux)
3. Connect the External probe or clamp to the input I1 of the instrument.
4. Check if the selector on the probe or clamp is adjusted according to the range
set in the instrument. Both range must be set to the same value.
Example of External probes connections
CAUTION
The OFF position of few probes send to probe's output the Battery voltage
(approx 9V which is over the expect full scale). This could influence the
measurement of the other instrument's inputs. So NEVER left connect to
instrument probes with the Selector placed in OFF position.
