6 Operang the instrument
Dierent measuring modes can be selected via the rotary switch.
When the instrument is in current mode , it automacally detects the range
and the type of measurement, AC or DC (testo 770-1/-2/-3 (0590 7703)).
When the instrument is in voltage mode , it automacally detects the range
and the type of measurement, AC or DC.
When the rotary switch is at the posion, the instrument measures
resistance, connuity, capacitance and diode test.
If the instrument is switched to power mode , it measures acve, reacve and
apparent power together with the power factor (for sinusoidal signals).
All the available measuring modes can also be selected manually.
Magnec suspension system (accessory)
You can use the magnec suspension system, which is available as an
accessory, order number 0590 0001, to aach the testo 770 to metal
surfaces.
The suspension system’s magnet must not come anywhere near the
clamp meter during the measurement (see graphic). Automac
adjustment of the measuring range could be inuenced as a result.
Do not hang the testo 770 higher than 2 m.
WARNING
Magnec eld
May be harmful to those with pacemakers.
> Keep a minimum distance of 15 cm between pacemaker and instrument.
CAUTION
Magnec eld
Damage to other devices!
> Keep a safe distance away from products that could be damaged by the
eects of magnesm (e.g. monitors, computers or credit cards).
