Manual Ranging And Autorange Mode; Battery Saver; Relative Measurement Mode; Rms Measurement - Bahco BDACM1000 Manual De Usuario

To enter and exit the Data Hold mode:
1. Press key (short press). Fixes the display on the current value, H is
displayed.
2. A second short press returns the meter to normal mode.

3.1.2 Manual ranging and Autorange mode

The Meter has both manual ranging and autorange options.
– In the autorange mode, the Meter selects the best range for the input
detected. This allows you to switch test points without having to reset
the range.
– In the manual ranging mode, you select the range. This allows you to
override autorange and lock the meter in a specific range.
– The Meter defaults to the autorange mode in measurement functions that
have more than one range. When the Meter is in the autorange mode,
AUTO is displayed.
To enter and exit the manual range mode:
1. Press RANGE key. The Meter enters the manual ranging mode. AUTO
turns off. Each presses of RANGE key increments the range. When the
highest range is reached, the Meter wraps to the lowest range.
NOTE: If you manually change the measurement range after entering the
Data Hold modes, the Meter exits this mode.
2. To exit the manual ranging mode, press and hold down RANGE key for
two seconds. The Meter returns to the autorange mode and AUTO is
displayed.
3.1.3 Auto power off mode
The Meter at the "auto power off mode" and
not used for 15 minutes.
Press the FUNC. key or rotate the rotary switch to wake the meter up.
To disable the "auto power off mode", hold down the FUNC. key while turning
the meter on.
display if the Meter is on but

3.1.4 Relative measurement mode

The Meter will display relative measurement in all functions except frequency.
To enter and exit the relative measurement mode:
1. With the Meter in the desired function, touch the test leads to the circuit
on which you want future measurement to be based.

3.1.5 RMS measurement

All the AC measurement values is the RMS (root-mean-square) values.
Frequency range is up to 1KHz sine.

3.2 Measurement Functions

3.2.1 AC and DC Voltage measurement

To avoid electrical shock and/or damage to the instrument, do not attempt to
take any voltage measurement that might exceeds 1000Vdc or 1000Vac rms.
The Meter's voltage ranges are 400.0mV, 4.000V, 40.00V, 400.0V and 1000V.
To measure AC or DC voltage (set up and connect the Meter as shown in
Figure 3-1):
1. Set rotary switch to the AC/DC V range.
2. Press the FUNC. key can change the mode of voltage test.
3. Connect the black and red test leads to the COM and V terminals
respectively.
4. Connect the test leads to the circuit being measured.
5. Read the displayed value. The polarity of red test lead connection will be
indicated when making a DCV measurement.
NOTE:
Unstable display may occur especially at 400mV range, even though you do
not put test leads into input terminals.
For better accuracy when measuring the DC offset of an AC voltage, measure
the AC voltage first. Note the AC voltage range, then manually select a
DC voltage range equal to or higher than the AC range. This improves the
accuracy of the DC measurement by ensuring that the input protection circuits
are not activated.
